I was a little hesitant with this recipe. I make a good banana bread and did I really need a different one - well apparently I did. It's another one from that Step-by-Step Breads book that I keep telling you to get. I think at this point I've tried almost every recipe in there. Sourdough Banana Bread (Adapted from Step-By-Step Breads ) 2 1/4 c flour 1 t baking powder 1 t salt 1/2 t baking soda 1 t cinnamon 1 t nutmeg 1 egg 1/4 c sugar 1/2 c brown sugar 1/3 c oil 1 c sourdough starter (at room temperature) 1 c mashed ripe banana (about 3) 1 t vanilla 1/2 t lemon zest 1 1/2 c raisins 1 c nuts (optional) In a small bowl mix dry flour, baking powder, salt, baking soda, cinnamon, nutmeg. Set aside. In a mixer beat egg. Add sugars and oil. Add the sourdough starter, bananas, vanilla, and lemon zest. Mix until blended. Gradually add the flour until mixed in. Stir in raisins. Pour into a 9x5 loaf pan. Bake at 350 (325 for glass) for 1 hour 10 min or until too...
