Cream butter, add salt, add sugar, gradually. Add eggs one at a time, beating well after each addition. Sift flour together with soda. Mash bananas with a fork, beat until light, add alternately with dry ingredients to egg mixture. No nuts in recipe, but you can add 1 c. chopped nuts if you want. Turn into greased loaf pan. Bake 1 hour at 350 degrees (sometimes a little longer), till knife in center comes out clean. I like to spread some butter over the top right out of the oven.
