yo what the fuck IS yeast? like i know how to use it in recipes and what it does, but how is it made? how did people use it in recipes thousands of years ago? cuz i don't think they went down to tesco and bought some instant yeast.
Yeasts are group of unicellular fungi, there are over a thousand different species. They mainly eat sugars and excrete carbon dioxide and ethanol, depending on how much oxygen they can get.
Like most similar organisms, they're basically everywhere, but obviously they grow best where food is available for them - on fruits, seeds and grains. If you mash that stuff up, chances are you'll get some yeast mixed in. Leave it for long enough, and you'll see carbon dioxide being produced.
Naturally occurring fungi but given the vast amount different kinds, that's how you can have two breads with exactly the same ingredients taste different.
Obviously they didn't have the technology to isolate specific types of yeast several hundreds of years ago, which is why starters were so important. If you had a good starter, ideally, as long as you kept it alive you could make good bread. Armies couldn't just carry around entire loaves of bread but with a few starters, flour, salt and water, they could help feed a vast amount of people on the go.
This article should answer most of your questions.
Yeast spores occur naturally in the air almost everywhere and also in flour. So when some neolithic gatherer decided to mix his grains with water he would have noticed it puffed up. And when he threw his ruined picking in the fire he would be amazed that it was actually delicious.
Ever heard of sourdough? Exactly the same idea. Pre-packaged yeast is just used for ease and reliability.
People have already explained some of it, but yeast has been sold as it's own product for thousands of years. Brewers were typically the people who sold yeast, which they made by mixing the foam scraped from the top of their fermentation vats with water and flour. This would either be sold as a liquid, or dried in salt and sold as a solid dry mass which would be crushed or shaved with a grater and mixed into bread dough.
yo what the fuck IS meat? like i know how to use it in recipes and what it does, but how is it made? how did people use it in recipes thousands of years ago? cuz i don't think they went down to tesco and bought a pack of sausages.
Yeast are eukaryotes and we use them as slaves to bake bread and make alcohol. Then we kill and dispose of them without so much as a "thank you" or even some kind of deferential ritual of respect that some hunters carry out when killing an animal. When I homebrew wine I always say thank you to the yeast I murder when I dump a teaspoon of sodium metabisulphite into my fermenter.
To put things another way, even PETA doesn't give a shit about eukaryotes.
Yeast is fungi but we do literally eat bacteria since bacteria is on everything, but we eat large amounts in certain fermented foods like yogurt, kefir, etc. Not really weird. A lot of food is made with bacteria as well like vinegar etc. but those things usually have the bacteria cooked.
Mexican Army patrol was attacked when they approached what they thought was a meat tree. When they came crawling back they were asked if they made it to the meat tree. They replied, "eet was not a meat tree, eet was a ham bush."
Speaking of all this yeast, I have been making lacto-fermented pickles. But it seems I'm often low on lacto-bacteria.
I have been wondering if I had a pussy to stick my hand in, it that would get my pickles going a little better.

Imagine if she wasn't just a cunt and could rely on previous workplaces to give her work when she needs it?
