Alternative Starches: How to thicken sauces without flour

November 19, 2019


If you want to make a gravy-type sauce without
the use of wheat flour as a thickener, you have so many good options. Whether you’re
cooking for somebody with celiac disease, or you just want to try some different textures,
I’m going to show you a few experiments with some widely-available things like cornstarch
and arrowroot — also, we’ll examine some more exotic options, like xanthan gum and
agar agar. “Please, agar agar is my father. Call me agar.” First, I think it’ll help to just remind ourselves
how starches thicken sauces in the first place. Let’s get our Alton Brown on. The big white
cotton balls there represent the water-based liquid that we’re going to try to thicken
— could be meat drippings, could be dissolved fond, milk, wine, whatever. All the water
molecules are spread out in a thin layer because there’s not much holding them together. The
sauce is loose, thin. Then we throw some starch into our sauce. These are tightly-packed carbohydrate
granules — little balls of sugar polymers that naturally occur in lots of plants, not
just wheat. Then we apply some heat to the sauce, the starch granules unravel and explode.
This is called gelatinization. Then you stir the mixture and the exploded starches bond
with the water and everything gets tangled together in a big web that traps the water
molecules in three dimensions — they’re heaped up on top of each other now, and our
sauce is thick. Thickeners can also keep fats from seperating
out of your sauce. If you add oil to your water-based sauce, it will naturally just
float to the top in a grease layer, because fat molecules are light and hydrophobic. But
add some starch and some heat — the granules explode and the water and fat molecules alike
are trapped in the same web, together. It’s not the most stable sauce ever, but starch
does a pretty good job of keeping sauces from separating. Now, not all of these starches are the same.
Some are little straight chains of glucose — that’s amylose. And some are big branched
chains of glucose called amylopectin. The primary practical difference between the various
kinds of cooking starches is the relative proportion of amylose and amylopectin within
them. The just have different properties in the pan, depending on that relative proportion. Now, when you thicken a sauce with when flour,
the most common way you do it is by making a roux. You melt some butter into a pan, stir
in enough flour to make a paste, you cook it for a minute, maybe you let it brown depending
on the flavor and color your after, then you gradually whisk in enough liquid to get the
sauce consistency you want, being sure to bring it to a boil, which is the temperature
that wheat starch needs in order to gelatinize. However, the most common way that people thicken
with alternative starches is with a slurry, and we’ll start with cornstarch. Brits would
call this corn flour, and that’s technically more accurate. Flour is a grain, root, bean,
etc that has been ground up into a dry powder. It might be the whole grain, as in the case
of whole wheat flour, or it might just be the white part of the grain, the endosperm,
in the case of this stuff, which is white wheat flour. Regardless, flour has stuff in
it other than just starch, most notably protein. Products that are sold as “starch” and not
“flour” generally have only starch in there — the starch has been isolated from the
other stuff, via some kind of chemical or physical process. “Cornstarch,” despite its
U.S. name, is not refined. It’s just white corn flour, but because corn endosperm naturally
has so much more starch in it than anything else, it basically functions the way an isolated
starch would, so I’m guessing that’s why it’s labeled as cornstarch in the states, even
though that’s technically wrong. Anyway. When people thicken with starches that aren’t flour,
they usually do it by means of a slurry. Gonna take a little bit of cornstarch, put
it into any kind of small container. I like to do it in a mason jar. In then you’ve gotta
mix in some liquid, and that liquid can’t be hot. Basically equal parts starch and liquid.
And then you could either mix that around really vigorously, or what you can do with
a mason jar or any other lidded container is … shake it up. Totally smooth. Then you just go over to the hot liquid that
you’re using for your sauce — I’m just using cartoned beef broth for all of these experiments
— and you just stir in enough slurry to get the thickness that you want. Different
starches gelatinize at different temperatures — cornstarch does it at slightly less than
a boil. The reason you do the slurry is to get starch
granules separated from each other. If you threw dry starch or flour directly into the
hot liquid, it would clump up — your sauce would be lumpy. That’s one reason that we
mix wheat flour into a roux — to get all the granules dispersed in the fat, away from
each other so that they won’t clump when the liquid hits the pan. But you can also use a wheat flour slurry
to thicken a sauce. That’s what this is. The problem is that, if you taste it, that sauce
has an unpleasant raw flour taste, which is a real thing. You’d have to simmer this for
a while to cook out that flavor, whereas if you cook the flour in a roux, that raw taste
goes away really really fast. Cooking flour in a roux does two other things
for you, though. If you let it brown a bit, it gives your sauce a nice brown color — without
using that bizarre “gravy browning” stuff that the Brits like to use. It’s basically
caramel water. Anyway, also, if you let your roux really brown, it gives the sauce a toasty
caramelized flavor. This phenomenon is used to the max in Cajun food — a culinary tradition
based on all of the different flavors and textures you can get by browning roux to varying
extents. So, since roux tastes good, I’ve always wondered
why people make a slurry with cornstarch instead of making a roux with it. Let’s try. Oh, hi! I guess you caught me editing myself.
I’ve just been listening to this with my new headphones, which are courtesy of the sponsor
of this video — Raycon. Raycon’s a cool company founded by Ray J. He was sick of premium
audio being so over-priced, so he got with some audio engineers and he came up with these.
Perfect bluetooth pairing — I don’t have wires dangling in my way. There’s a microphone
in them for phone calls, and you know, they sound just as good as other premium audio
brands, but start at about half the price. For video production purposes, what’s really
nice is the flawless noise-isolating fit. I can be reasonably assured that what I’m
hearing in my headphones is what came through my microphones, and not the sound that’s just
around me in the room. Click my link in the description below to get access to Raycon’s
Black Friday and Cyber Monday deals. I can’t even tell you how good the deals are gonna
be — you’re gonna have to check it out on the site. Anyway, we were about to hear,
see and smell what happens when you try to make a roux out of cornstarch. Hmm, it’s putting off some weird smells. Whisk
in the broth, heat it up to gelatinize, and give it a taste. That has a kinda funny flavor
to it, but frankly I think that cornstarch always has a kinda funny flavor to it. Some
people describe it as chalky, or I kinda think of it as rubbery or kind of chemically. Anyway,
it’s not a really big deal and it goes away after you cook it for awhile. One thing I like about the cornstarch roux
vs the cornstarch slurry is the roux version is more opaque. Normally cornstarch-thickened
sauces are kinda clear, I would guess because cornstarch has so little protein in it, and
if you’re trying to make gravy, clear gravy is kinda weird. Let’s try something else. This is potato starch, very common in U.S.
grocery stores. If it’s not next to the cornstarch, it might be in a kosher foods section. Jews
aren’t supposed to eat grains at Passover, so potato starch. Slurry goes in. That thickens at a way lower
temperature, and it is clear as glass. It also doesn’t have any funny flavor. Totally
tasteless. People say that you shouldn’t bring potato starch to a full boil because that’ll
cause it to break down quickly. If you cook any starch long and hot enough,
those glucose chains will start to break apart and then water molecules fall out of the web.
The sauce thins out again. But I boiled this for a very long time, adding
water to compensate for evaporation, and I didn’t really observe any breakdown. I did
the same thing with my cornstarch, too. I boiled it hard for like 20 minutes, nothing
seemed to thin out. But even if it did, you could just mix in a little bit more slurry
to compensate. I think a lot of the differences between different
food starches that you read about are really only an issue when you’re making food at a
commercial or industrial scale, when very tiny differences can multiply into huge differences.
When you’re cooking at home, things are just way less sensitive, and you can easily compensate
for stuff. OK, now things get interesting when we try
making a roux out of the potato starch. Browned potatoes taste really good, so I’m betting
this is gonna taste really good, and indeed, the resulting sauce is delicious. It’s still
a little unnervingly clear, but man that tastes really good. We get very similar results from rice flour.
Again, a pretty widely-available item. It’s not an isolated starch — it’s just ground-up
white rice. Slurry goes in. That has to come to a good boil before it thickens, and it’s
slightly more opaque, probably because it’s a flour — there’s stuff in there other than
just starch. Totally neutral flavor. But when we make the roux with rice flour, we let it
brown a little bit, whisk in the broth, and that is again, delicious. No surprise there,
right? Rice that has been browned always tastes good, and I like that this version is not
as translucent as the potato starch gravy. That’s good gravy. Let’s run through some other starches real
quick. Here’s tapioca — a starch extracted from
the tuber known as cassava or yuca. In the slurry goes, very nice clear sauce, but I
think it has kind of an unpleasant, slimy texture on the tongue. It’s also reputed to
do weird things when you stir it a lot while cooking, it kinda clumps up. Not a fan. Tapioca is often used in desserts, like fruit
pie fillings. It is reputed to freeze and thaw really well. It’s also supposed to stand
up to acid really well. Acid can break down starches and thin them out. Is that danger
relevant to sauce-making? Well, if we put some vinegar and a pinch of sugar into this
gravy, you have the base of like half the gloopy sauces you know and love from Chinese-American-style
restaurants. Pretty tasty stuff. I tried making the same sauce with cornstarch,
which is reputed to be easily broken down by acid, and I noticed no such problems. Maybe
a savory sauce just isn’t acidic enough to break anything down. And if the sauce did
thin out, you could just put in more slurry. Cornstarch: very popular in Chinese-American
restaurants. Here’s arrowroot starch. I think that the
dried product has this weird minty smell, but the sauce thickened with the slurry is
nice and clear and has a neutral flavor. People say that arrowroot sauces don’t reheat well
— they break down easily. Well let’s try pouring this off, refrigerating it for a while
and then reheating it in the microwave. I notice no thinning at all. In fact, it’s nice
that it reheats smooth. When you reheat sauces made with wheat flour
or cornstarch, I often find that I can’t get them smooth again, no matter how hot I get
them. This is the cornstarch-thickened sauce — really gloppy and jelly-like, even though
it’s really hot. Not nice. Arrowroot has another bad reputation, which
is that it does weird things in dairy. I’m just thickening some milk with arrowroot slurry
and indeed, that has a super weird, slimy texture. No good. Alright, so those are the big root, tuber
and grain starches. Let’s experiment with some more exotic stuff. This is xanthin gum.
I bought this down at my normal grocery store the other day. It is a very popular additive
in industrial prepared foods. It’s not technically a starch. It’s another kind of polysaccharide
made by fermenting sugars with a particular kind of bacteria. First I tried making a slurry with it, and
that did not work at all. It clumped up the second it hit the water in the jar. The package
suggests mixing it in with an oil slurry instead, and indeed, xanthin gum disperses very easily
and smoothly into fat. You gotta give it a few minutes to gel up, but then a tiny amount
of it has incredible thickening power, and that sauce has a really pleasant, smooth mouthfeel.
Xanthan gum is often used in ice cream for that nice smooth mouthfeel it gives. I figured because it disperses so well in
fat, maybe it’d work well in a roux. Yes, I made xanthan gum roux, and the resulting
gravy had a totally different texture — chalky, powdery, gross. Couldn’t tell you why that
happened, but don’t do it. One thing I can tell you about xanthan gum
is that you don’t have to get it hot. It gels at virtually any temperature. I’ll show you.
That’s room-temperature broth. Scatter in some xanthan gum, it clumps up really bad
in water, but if you stir it around and then let it sit for a few minutes, it thickens
up without any cooking at all. Now I’ve seen so-called “molecular gastronomy” chefs do
this and then either try to blend out those lumps with an immersion blender or strain
them out. But, remember that zanthan gum does dissolve
very smoothly in fat. There, you can see why this stuff is a very popular thickener in
pre-packaged salad dressings. We’ll mix that oil into the broth, let it sit for a few minutes
and it gels right up. It looks kinda gritty, like apple sauce, but tastes smooth. Now,
watch this, I’m gonna get it really hot in the microwave, and the texture is exactly
the same. That is exciting. When you thicken a sauce with a starch, the
viscosity varies tremendously depending on the sauce’s temperature. That’s why when you
make, say, a pot pie, you gotta let it cool a long time before you scoop it out, otherwise
the sauce will just fall right off the other ingredients and run out all over the plate.
If you thickened your sauce with xanthan gum, it would be the same thickness regardless
of whether it was pipping hot or lukewarm. That’s awesome, so this is something that
I’m gonna need to experiment with more down the road. One more experiment right though now — agar
agar. “Call me agar.” This is a mixture of a polysaccharide and a pectin derived from
algae. It’s used in packaged foods a lot, and it’s also a vegan replacement for gelatin,
which comes from animals. Agar powder dissolves really easily into water.
You do not have to make a slurry with it. And when you bring it to a boil, the sauce
has this texture of a reduced meat stock — more kinda unctuous than thick. But let’s try the
Heston Blumenthal trick. Heston boils in some agar, then he puts the sauce in a jug and
chills it. Now it’s like a very stiff jello, but unlike jello, it is heat resistant. That
will not melt when you get it hot again. So to turn it into a sauce, Heston busts it up
with a stick blender. And that looks like regurgitated dog food. And the texture is
repulsive — a foam made up if tiny little rubber beads. Thinning it out with more broth
does not help. Sorry, Heston, I think I did it wrong. Come
to think of it, when I saw him doing this on one of his shows, he was doing it with
a dairy-based sauce, and I’ve read that agar reacts differently with dairy. I might have
also just used way too much. More experimentation is needed there, but I hope you’ll find my
more successful experiments here to be useful to you. I think the big takeaway here is that there
are lots of food starches, and they all work. But, since Thanksgiving is coming up here
in the states, I’ll just stress again that if you need to make a gluten-free gravy, you
can try making your roux with rice flour or potato starch — I’d do the rice flour because
it’s more opaque. That makes a really delicious gravy. Nobody is gonna miss the wheat.

    When I started watching cooking videos on YouTube I was surprised how many people used flour to thicken gravys, as I had never heard of doing that. My family has always used corn starch so when my Grandfather and Mother were teaching me how to cook (fun memories) I never saw/heard anything different.

My hands down go to flour replacement is Pillsbury Best Multi-Purpose Gluten Free Flour Blend, it's not quite like flour but it's close enough to where I have made cookies with it and no one suspected they were gluten free. I use it to make gravy and also deep fry chicken (with some added corn starch and a pinch of baking powder). Yes, I know I sound like a commercial but it's really great stuff.

    I haven't loved a video so much since Alton Brown went off the air! Terrific job, Adam! I really enjoy the technical information you include in your videos, especially this one!

    6:40 WHY are people including you referring to flavours as "chemically"!!!!
    Chemicals are in almost everything on earth but now the words being flung around to describe an unusual taste! This needs to stop

    I know this isnt about cooking but Can you please talk about the YouTube coppa deal? AND PLEASE mention it's not about government censorship but about how YouTube sold kids personal information for profit illegally and the new shit youtubers have to do is the the response YOUTUBE is making so they put the liability on youtubers and avoid fines for continuing to sell kids personal info

    I know you didn't mean anything by it Adam but try not to say Jews and instead try Jewish, Jews comes off as a slur to some Jewish people

    Agar will melt when exposed to heat. In fact, it will melt and reset after the application of heat indefinitely, unlike gelatin.

    Another property it has which is different to gelatin is that it will set at room temperature, and this gives a different texture to agar which sets in the fridge.

    I love love love how much research and detail you managed to put into this video, without making it very long! The one thing I'm missing, though, is some kind of comparison chart at the end. Perhaps you could do a blog sometime where you go over some details from your videos?
