Sorry, no pics, but my 8-year-old is learning about making yeast breads.
Today was classic white bread - only 6 ingredients. And she knows how "the yeastes" work to make the dough "poofy". And how they get poofy again in the bread pans. And how its kind of gross how the yeastes eat the sugar and make gas.
And she knows that we don't grow wheat, which is what it takes to make flour...
Maybe next week we will make corn bread and she can learn about how double-acting baking powder and eggs can substitute for the "yeastes" that we put into the wheat flour...
