2 Tbsp. cornstarch
(One of my favorite cooking tips is used with butter. Whenever a recipe tells you to "cut" in the butter, chill the butter and then shred it into the flour with a large cheese grater. The butter melts in perfectly during baking!)
2 cups flour
Toss the liquid mixture into the dry mixture but do not mix too much. Drop by spoonfuls on the hot fruit. Pat smooth. Sprinkle with sugar and bake at 400 degrees for 20 minutes or until the topping is golden. Serve warm with ice cream or half and half.
