I found this recipe on the internet......... I found it several places, so I think it's okay to post it:
1/3 cup shortening
1 cup sugar
1 egg
2 cups all-purpose flour
1 tsp baking powder
1/2 tsp baking soda
1 tsp salt
1 cup mashed banana
1 cup sourdough starter
3/4 cup chopped walnuts
1 tsp vanilla or 1 tsp grated orange rind
Cream together the shortening and sugar, add egg, and mix until blended. Stir in bananas and sourdough starter. Add orange rind or vanilla. Sift flour, measure again with salt, baking powder, and soda. Add flour mixture and walnuts to the first mixture, stirring just until blended. Pour into greased 9x5" loaf pan. Bake in moderate or 350 oven for 1 hour or until toothpick comes out clean. Cool before slicing.
This is some of the best banana bread I've eaten, and I'll be making it again............soon! I modified it slightly, I used butter instead of shortening and I would have liked to have used sucanat instead of sugar, but I'm out until my co-op order goes in. So, I subbed 1/2 cup white sugar and 1/2 cup honey and I didn't use nuts because those aren't gastroparesis friendly! I think this might work well with a gluten free flour mix, too! If you try it, let me know how you like it!
