Totally versatile! I've made it with blueberries, apples, orange zest, plain. It's just good stuff. Normally I halve it and make it in a nine-inch cake pan. I actually found the recipe in an ancient southern cookbook called "Charleston Receipts" while I was down in SC. The only real change I make is to sub yogurt for milk as I find it gives it a moister, more coffeecake-like consistency.
