Black walnuts are native to America and taste nothing like the regular English walnuts sold at the grocery store. You may have to purchase these online, but they will change the taste (for the better) of any recipe you use walnuts in.
1 cup shortening
2 cups sugar
1 1/2 cups banana -- mashed
2 eggs
1 teaspoon vanilla
2 teaspoons baking soda
1 teaspoon baking powder
2 teaspoons lemon juice
3/4 cup milk
3 cups flour
