Buckwheat Sourdough Bread II

This time, I added 1/2 tsp. of instant yeast to help the rise...which it did-then I overproofed it! Duh.

Still, the crumb is lighter, and I think the use of AP flour rather than strong flour helped with the crust-it is very crackly.

I am so close to the perfect buckwheat loaf. Frustrating, but exciting as well.
