These rustic desserts are an ideal way to showcase seasonal fruits. They're so simple and require only a baking dish, some fruit, and a few other ingredients.
Ripe, fresh blueberries are perfect for this dish, though frozen berries will also work. But keep them frozen, and bake the crisp 10 or 15 minutes longer as needed. Thawed berries are too fragile to toss and give off lots of liquid.
