Baking With Yeast

Yeast is a single celled fungus related to mushrooms. There are more than one thousand 500 recognized species of yeast in the world. When you mix flour, water and yeast together, the yeast eats the simple sugars in the flour and poops alcohol, carbon dioxide bubbles and molecules that we consider flavor into the doughy mix. You don't technically have to buy yeast. If conditions are right, naturally occurring yeasts that live in the air around us can be captured by making your own baker's yeast.
