Eric made this beautiful bread with 2 cups of natural yeast and only half as much commercial yeast as a normal recipe called for. [The recipe made 3 loaves - it's the baguette recipe from the book below. Bread snobs know from the pic it's nowhere near the traditional stuff, but it's delicious.]
So far we're loving bread this way. I like the taste of natural yeast and we're getting a good rise with much less of the commercial stuff.
Eric's favorite bread book is The Bread Book, by Linda Collister and Anthony Blake is out of print and dirt cheap on Amazon. He likes it for the instructions and for the range of recipes.
