Could you grind up a loaf of bread back into a flour and make a new loaf of bread?

How was it?
Varyk@sh.itjust.works 1 day ago
pretty rough and crumbly and crappy.
it was impossible with the kitchen tools I had on hand to grind it into a fine enough flour to my liking, I just had a generic blender, but my whole reasoning for the experiment was “i bet I could make bread out of bread.”
and it was moderately successful in that regard. what emerged was properly identified as bread.
although I chucked most of the loaf in the trash because that was its flavor profile.

Not really, no - entropy is one-way at the macro scale.
The flour absorbed water, and combined with kneading, produced gluten.
Grinding it all up wouldn’t reverse that process - it would just be ground up bread.

With enough energy you certainly could, even if that meant breaking everything down to their constituent parts chemically and doing stuff like reconstructing proteins from amino acids.

There is probably a law of diminishing returns in here because bread contains other ingredients as well (salt, yeast, etc.) and after a while the chemistry of baking will be out of whack.

I’ve heard of some bakery somewhere doing “recycled bread”, where they supposedly take the leftover bread that didn’t sell that day, dry it out, grind it up, and mix it with fresh flour to make new bread, but I don’t know for sure if the story is real.

If a real thing in Mexican bakeries. They’ll take all the stale pan dulce, waiting till they become very dry, and grind them into a flour, or fine chunks depending on the bakery, and mix them in with fresh dough to create a cinnamon flavor pastry called a “piedra”, or rock in English. They’re pretty good. my dad loves them.

TIL

Its a real thing, there’s a term for it if i can find it.
altima_neo@lemmy.zip 1 day ago
That’s somewhat different. They aren’t taking stale bread and reusing it to make new bread, but rather a portion of the raw dough from a previous batch is saved and added to fresh dough. It’s meant to add a bit of fermented flavor, without quite being a sourdough. It’s more in line with preferments like poolish and biga.

It’s common in Germany

During COVID lockdown I had plenty of yeast but very little flour, so I bulked it out with about half Matzo meal, which isn’t breadcrumbs but the flour has been cooked. It wasn’t great, but it loafed enough to slice and make sandwiches or toast.

Yeah but the texture would probably suck
OprahsedCreature@lemmy.ml 1 day ago
Croutons are cooked twice with no problems. Once the bread gets stale it probably grinds easily.

Actually I know somebody who makes cake out of it.

Binging with babyish on YouTube tried this not long ago when trying to make cheeseburger pizza or something. It wasn’t great

The gluten does not come back if u pulverize it. You’ll likely end up someone terrible.
Jimmycrackcrack@lemmy.ml 1 day ago
They might end up making a pretty crappy load of bread but it’s a bit much to imply they’ll become a bad person because of this.

I’m going to edit but change the context cause this made me smile.

You made shitty bread, when you could have made good bread. Straight to Jail.

If the bread is just stale you can restore it by wetting it and heating an oven or microwave.
AnyOldName3@lemmy.world 22 hours ago
Partially restore it. At best, you put about 60% of the water into the starch crystals that the bread had when it was fresh. It’s a massive improvement, but it’s not hard to tell which is which in a side-by-side comparison.
altima_neo@lemmy.zip 1 day ago
I haven’t tried it. I can only assume you won’t get much gluten development. It might be more crumbly and dense, like cornbread, I would think.

Ehhhhh, no, not unless you really want to fuck around with the meaning of “bread”.
The end result of baking bread isn’t just flour with air in it.
The proteins change, the starches change, and you can’t just undo that by grinding the bread. I would say that anything that would undo those changes would essentially be making something else entirely, but it definitely isn’t going to be ingredients that v AC c be fermented and turned into anything resembling bread anyway.
Now, you can make loafs out of ground up bread. You can essentially grind up damn near anything edible and mix it with binders, then make it loaf shaped and bake it though. If you want to get frisky, bread pudding is just using bread to make a loaf of something. Meat loaf ain’t bread, but it’s the same basic idea as bread pudding (again, if you want to fuck with word meanings).
But there are more things than bread pudding you can turn bread into. They’re all similar, because there’s only so many binders that are edible in the first place. But they’ll have different textures than bread pudding, and pretty much any flavors you want to try.
But bread, even if you deal with things that aren’t wheat, you’re causing chemical changes at such a level that there’s no way to turn it back into something that will perform the same as flour

The meaning of bread is pretty loose as it is, especially internationally.
Nurse_Robot@lemmy.world 1 day ago
To be fair, you can unboil an egg. So I’m not sure how it would taste, and I’m not aware of it ever being done, but I’d hesitate to say it’s impossible
southsamurai@sh.itjust.works 1 day ago
I had to look that up, and it’s pretty cool, but what you’re getting back wouldn’t work right as an ingredient, except in some edge cases maybe. Plus, nothing I found indicated that the urea was for sure removed, which would interfere with cooking. I also didn’t see anything about the fats and what kind of shape they’re in.
It’s also not the same thing because that’s a chemical change, not grinding the egg up. Which you can do to bread too, but what your get back isn’t flour at all.
Assuming that you could use the same basic idea with bread, what you’d get is a slurry of gluten, and broken down starches. There’s stuff that could maybe be done with that, but not making bread for sure. For one thing, the yeasts consumed the sugars, converted it to gas and alcohol, most of which evaporates out by the time you slice bread. So the process is dead in the water at the start. You’d have to add back that stuff in a form that could be fermented, and that’s basically just going to be flour.
Tbh, saying that the process I saw is unboiling an egg is journalists licence at best, click bait bullshit at worst, like the whole dire wolf thing that’s been making rounds lately. Yeah, if you want to pretend that “unboiling” means something other than what the obvious assumption is going to be, that’s great. But the process doesn’t actually return the eggs did the state they were before. Pretty close, since egg proteins are relatively simple, but it isn’t like what you’re getting is the same thing as if you whipped up eggs in a bowl, which is what “unboiling” would mean to most people (and that’s the main complaint I saw on videos and articles).
The people that cooked it up (heh) even said that it’s more about being able to clean gear and get a partial return of the proteins for reuse, with the key word being partial.
