How a Chemist Makes the Softest Bread You'll Ever Eat

[@ACSReactions]

The thing about bread is that there are So. Many. Kinds. You've got yeasted breads. Sourdoughs. Flat breads. Steamed breads. Matzoh and lefse and chapati and focaccia and lavash and baguettes and naan... we could go on, and there's science in each of them! So leave us your favorite breads below and we just might do some digging into what makes them so delicious!

[@defeatSpace]

and then you have tarts...

Brioche, Brioche, Brioche! Please, please, please do brioche! 🙏🏼🙏🏼🙏🏼 This is the most challenging bread recipe for me. I’d adore you for explaining the science behind what adding butter does to make brioche so a-mazing. The guys explain how to make it, but I’m a curious kitten. I want to know exactly how & why. What is the alchemy behind this fantastic French/German bread revolution of “breaking” butter into the bread dough. 🤯🙏🏼💜

[@crystalheart8535]

Can you please do a video on role of both gluten powder and bread improver together in a tangzhong dough? Please 🙂

[@gnewman18]

You might want to try accounting for the extra moisture in the 12% bread in the main recipe. You may already have figured this out but extra time is not the answer (in my opinion) the dough hydration is the likely culprit. There are plenty of videos that will show you this. I very much apologize if I am breadsplaining to a real chemist. I just love to bake 😊

[@sumdumbmick]

I make a bread that's so soft it can't even be made into a loaf, because if you tried to pick it up as a loaf it would bend. all I do is add yogurt and olive oil to the dough, and then bake it with steam. vary the ingredients slightly and you can get a ciabatta, focaccia or naan. it works nicely as the base for pizza, khachapuri, melonpan, doughnuts, waffles, etc.

[@kevinu.k.7042]

Great video... Lovely presentation and production. Just a fact correction. China learned to bake bread from European Jesuit Monks. Japan learned from French Bakers. They are very much the new commers to bread making. Japan really only started baking in the early 1900's. Both countries were taught flour scalding by their respective sources. Scalding flour in hot water for bread is well over 2000 years old in Europe. The French of course called it a Roux. Northern Europeans called it a 'Scald' in their various languages. The U.S. has 'rediscovered' this from the Chinese and Japanese. It's almost gone right around the globe. Though I am sure immigrants from Northern Europe would have brought this technique to the U.S. especially with their rye baking. A scald, Yudane, or Tangzhong doesn't have a huge effect until you get up to about 15% (measured by flour weight against the total flour weight in the recipe). A safe top figure would be 35%. However it is dependent on the glutenin quality and strength in the flour. The more gluten and the higher the quality of it, the more flour can be scalded and still be supported in the dough. My range is a safe 20% - 30%, the accepted range is 10% - 50% amongst Pro. and home Japanese bakers. But at under 15% the effect is very slight. I really don't know what you did to get that 12% Yudane result! Chuckling away here, in a friendly manner. We've all had our disasters. Finally, a properly used Scald *increases* the loaf volume a lot. Modern commodity wheat flour develops strong gluten which acts like elastic restricting the expansion of the dough. The gelatinised starch weakens this (as you said) and allows the loaf to expand more easily. I do hope you don't mind all of this input. It's not critical, or damming, you do excellent videos and it's a joy to see someone bringing the science out of hiding. . Thank you for a delightful video. 👍 Pst! - It's Yu-*Dah*- ne

The chemistry I wanted to learn in college.

[@redstarchrille]

One has to do the basic Chemistry at a university, then understanding the chemistry of the kernel and plant fysiology, then understanding the diffrent properties of the flour compound. But no bakers know this, only thoes that select the right mix att milling plants, or hipsters :P, that want to buy raw grains and make their own flour.

15:07 Reheat dry bread in the microwave, _with a cup of water._ The water will evaporate and soften the bread better. (But it will still dry out fairly quickly, so do it right before use.)

Great channel.

[@chrissquarefan86]

Thank you for this video! I'm using pre-cooked starches as egg replacer in baked goods (cakes, breads, even fancy stuff like eclairs) and they do make wonders! I notice that different pre-cooked starches have different characteristics. For example, pre-gelatinized potato starch maintains moisture and viscosity in baking for longer times, whereas pre-cooked corn starch bakes faster. I have to appreciate the use of the thermometer here because often times I found that if the starch is not fully gelatinized, the results are not as good.

[@Bradleyscience]

Your presentation was extremely well done and quite insightful. Chemistry can be fun! A fun thought for those tubers, they used to be poisonous. Cheers

[@AntonioSaiz]

I was expecting your bread recipe in the sources

[@ACSReactions]

Oops, that should have been in the description and it's there now. Alex looked at a lot of recipes and videos, but the basic outline she followed was from the New York Times cooking.nytimes.com/recipes/1016275-japanese-milk-bread

[@AntonioSaiz]

@@ACSReactions Thanks a lot! :)

[@CP-fe6jr]

If you cook a large spud in the microwave, then pass it through a ricer, add it to your dough (adjusting the other ingredients to suit), you get a very similar result. I'm now wondering what will happen if I combine both techniques together. I'll try it with my next batch of bread.

[@Coppertoe]

Thanks for a great explanation! I believe the flour & liquid are not supposed to simmer when making a tangzhong because of something to do with keeping the alpha-amylase enzymes and the beta-amylase enzymes intact "which can turn the dough to mush" somewhere after 74°C according to Peter Reinhart. I don't know if I explained it correctly... he talks about it on pg.71 of his book, "Whole Grain Breads." Try making your 12% loaf without boiling the tangzhong. Just heat the flour & liquid till thick, about 66-74°C.

[@NZtechfreak]

I regularly make milk bread with 20% Yudane (like a 4.5kg batch most weeks), no issues with structure or rise even though mine is more enriched than this through the addition of butter. Suspect following the dogma of 1:5 ratio making the tangzhong is to blame. Novita Listyani is the channel to follow if you really want to know about yudane/tangzhong.

[@fycafyca3588]

Very interesting video. The sources in your description provide a link to a video that seems to be different from the content of this video, your content is more closely relate to their newer video on tangzhong, the one they were talking about tangzhong 1:5, I wonder if that new video is your actual source?

[@Ulthar_Cat]

I think I know what went wrong with the mutant bread XD I think you're supposed to measure everything for the common loaf beforehand and THEN take flour and liquid from the measured ingredients to make the tongzheng, not from outside the recipe. Law of preservation of matter, your breads will have the same ingredients going in 💜 no more slimy dough, no more raw droopy bread XD 💜💜💜

[@yashwantgarud8967]

would the heating process not evaporate the liquid a bit?

[@Ulthar_Cat]

@@yashwantgarud8967 only a bit. Not enough to dry up the tongzheng. After my comment, I made the thing as I said, and it was fluffy and soft and delicious 💜

[@ErikratKhandnalie]

I kinda wanna see you redo the 12% bread and try to make it workable. Also, someone send this to Adam Ragusea.

[@AlexDainisPhD]

Honestly, I wish I'd had time to do it before this video came out, because I think I know how I could make it work and make it delicious. I'll definitely make a follow up when I can!

[@ErikratKhandnalie]

@@AlexDainisPhD yay! look forward to it

[@anaxiomenes3964]

Enjoyed the compactness of your lab presentation on an aspect of applied food chemistry. May I have a request? Could you consider giving a lab presentation on obtaining in a home kitchen the “perfect French fry”? That is, crispy and golden on the outside; fluffy and slightly firm (not mushy and flaccid) on the inside. Many professional cooks have attempted to give a satisfactory recipe. Not aware that anyone has tried to explain the chemistry behind it. One’d think the ASC has the scoop on this subject. Thank you for your outstanding effort and time in promoting applied science.

[@Jeremy-fl2xt]

This video was awesome, and I generally don't even eat bread.

[@jamesonstalanthasyu]

Is the texture why they cut it so thick? Or is there some other historical reason?

[@binaryguru]

I automatically knew this video was about scadling flour, I do it all the time. It also makes your bread last much longer.

[@davidhansson7041]

In Sweden were I come from sometimes rye flour is scalded. Boiling water I poured on the flour a couple hours or more and letting it swell before baking to make the bread softer and tastier. Now I know why that would be. Thanks!

[@BRUXXUS]

I love this stuff so much! I've been perfecting my pizza dough recipe and process over the last 2-ish years, and it's real good, but now I'm wondering how it'd behave with some yudane in the dough. 🤔 I mean... I like the more chewy and substantial NY style crust, but might be interesting to see how it reacts under the much higher heat used for baking a pizza.

[@ACSReactions]

That's an interesting idea. Let us know how it goes if you give it a shot! In the meantime, did you see our Better Pizza Through Chemistry episode with Peter Reinhart? kzbin.info/www/bejne/o2STiqGre56pi8U

[@BRUXXUS]

@@ACSReactions Definitely! I try to watch all Reactions videos as soon as I can. :D I'll report back on this test next time I make some pizza. I'll split the dough so I can also have a control group. hehe.

[@Deepa0309]

I love the way u have made the video , keeps it from being monotonous.😊

[@uisqebaugh]

I've always added cooked rice to my bread. The cooking of rice also creates gelatinized starch (which is why it is sticky).

[@MaxMcAdams]

[@my_granny]

ooh, nice! I wonder if you could replace some of the flour with straight up wheat gluten, to provide more structure. I don't know enough about baking to even guess at what amount, though.

[@ACSReactions]

Try it and let us know how it goes!

[@krisgerber7217]

Add the vital wheat gluten on a per-recipe basis and not to the entire bag of flour. The standard gluten/flour ratio is 1 tbsp. (15 ml) for every 2 to 3 cups (473 ml to 711 ml) of flour. [2] 2 Mix in the vital wheat gluten before you add the other dry ingredients. I used to do this for fresh whole wheat flour yeast bread and sometimes still do for sourdough

Also, you can take your stale bread cut into cubes, give it a toss in some cooking oil with salt and pepper and boom, 6 minutes later croutons will be born from your oven or air-fryer.

[@Dodo-td1pg]

Why does adding portion of pre-gelatinized mix make bread fluffier? At the end, all mix is gelatinized anyways?

As a semiotician I find it curious that when I think of "regime" I think of China and then 2 seconds later you say "China". Awesome video, I live live love the indepthiness of the entire process.

[@trains4nothng]

if you lower the dough weight of your final shape you can get rid of the line of compressed dough at the bottom, thank you for the video it is very useful you should make a follow up video with oatmeal molasses bread, potatoes bread, tortillas and pate choux(please explain the mystery of why pasteurized eggs wont work for pate choux probably something to do with lecithin degradation but i am just guessing).

I was curious about the way Japanese bakeries make bread and just watched a video last week or so showing the whole process for a specific bakery, but it turns out that for this bakery they not only don't seem to use yudane, they also don't use eggs... Still, it was a very interesting process to watch, here: kzbin.info/www/bejne/m2GZpoGNeMdsb7M It's like part store and part industrial setting, with them having only bread to sell with a few variations on ingredients, which... is kinda unique. Most bakeries I've seen in Japan had like this overflow of different stuff to get. I also remember watching something about a Japanese bread machine that used rice to make bread, really wanted to taste some of that to see how it works out... xD I think the bread fever in Japan died off a bit, but back on my first trip there they had bakeries everywhere with so many types of bread it'd take days to taste them all... we even went to a restaurant that had a full course of several types of bread for lunch. Funny enough, the one I remember most and that I ate.... just too much, I got it almost everyday when we were coming back to the hotel because a local market had it, was a melon pan of the industrial type. But it was some limited edition with actual melon flavor and a bit of sweetness to it, super fluffy, it was midway between bread and a moist sponge cake or something. This was some 15 years ago so it probably doesn't exist anymore, but man, that thing was totally addictive. After a full day of walking around, it was just like the perfect thing to get some energy back. xD
