My friend has been sending me pictures of all the baked goods she has made recently. She must be so talented to be a baker!

Does she bake breads?  I love breads baked with beer froth (discovered by the Gauls) because is controlled yeast in the dough.

Yes, but I don't think she has ever used beer froth before! Can you tell me more?

Bread has to proof, or rise, before baking.  The process is known as fermentation.  Beer froth helped this process.
