When making fresh desserts in summer, you don't have to eat them all at once. Whole desserts (cobblers, pies, cakes, etc) can be frozen once cooled. When ready to serve a frozen cobbler or pie, DON'T defrost it - put them straight in the oven! It will take a while (about an hour for a blackberry pie), so pop it in while dinner is baking. Then you will have a warm dessert ready for the end of your meal.
HINT: Pyrex makes freezer-to-oven dishes. Use the plastic lid in the freezer or fridge, and the glass lid for baking.
