Why This Recipe is a Winner

What Blueberries are Best?
Look for blueberries that are plump and smooth-skinned. The color of the berries is an indicator of ripeness (not the size of the berries), so choose berries that are deep purple-blue. You can use fresh or frozen blueberries with this recipe. Frozen blueberries are great because they’re frozen at the peak of ripeness and they hold their shape better while cooking.

What’s the Difference Between a Crumble and a Crisp?
Both a crumble and a crisp are used to describe a delicious fruity dessert with a streusel-like topping. A crumble has a denser, thicker crust on top. However, others have noted that crisps include oatmeal, whereas a crumble does not. Either way, clearly the lines have blurred between the crisp and the crumble, and today just about anything goes.
Serving a Crumble
Serve a blueberry crumble by spooning it into individual serving plates and top it with vegan ice cream or some coconut whipped cream. Then drizzle some of the blueberry sauce at the bottom of the pan over the top of the ice cream for a dramatic finish!

To serve, sit it out at room temperature for 30 minutes to an hour. Then reheat in the oven at 350°F for 15 to 20 minutes, until heated through.
