Blackberry Crumble FAQs
Can You Make Blackberry Crisp or Crumble with Frozen Blackberries?
Yes! Frozen blackberries work very well to make a crumble or crisp. I actually prefer using frozen blackberries instead of fresh to make this recipe for a few different reasons:
- Frozen berries yield a juicier fruit crisp.
- You can flash-freeze your own berries when they’re in season. But even if you buy frozen berries, they’re frozen at their peak of freshness, which ensures the best flavor and most nutrition.
- Last but not least, frozen berries are available year-round and are more affordable than fresh berries.
Does Blackberry Crisp Need to be Refrigerated?
Nope! That is, unless it’s really hot in your kitchen.
Store Blackberry Crumble for up to 2 days in an airtight container (or wrapped well) at room temperature. After that, move it to the fridge for up to 5 days more.
How to You Keep Crisp or Crumble Toppings From Getting Soggy?
I have 2 tips to help prevent your fruit crisp or crumble topping from getting soggy:
- If there is excess liquid on top, dab it off with a paper towel before storing leftovers.
- Reheat leftovers in the oven instead of in the microwave.
