whatis baking likeduring prehistoric times?

Answer 1

Baking requires the use of yeast- and that is rather advanced technology. SFAIK the egyptians used yeast for bread making, as luxury goods - hence the use of "unleavened bread" by the Jewish slaves

Baking also requires some form of oven- which means that the minimum rerquirement is bricks or solid stone structures. A metal container may also be used as an oven. All the above are civilisationnaly fairly advanced constructions

So, IMO, baking in prehistoric times took the form of cooking a mix of ground up grains on a flat rock, heated in a fire

Answer 2

First, is that before or after the discovery of fire?

If after the discovery of fire, they still didn't "bake". No cakes around back then. Muffins either. They stuck some meat on a stick and put it in the fire until it stopped bleeding. LOL

The use of real cooking tools wasn't discovered until the ancient egyptians (I think), but either way it was WAY after "prehistoric times".
