Over the years I have used this recipe for all kind of fruits and berries and never had a bad result. I have added a little cinnamon to the fruit from time to time. Vanilla adds an extra dimension to the batter, but I love it just the way I made it as a girl.
If you use a fruit that is not very juicy, you might add a little more juice. For example, I add about 1/2 cup of apple juice if I use apples.
