Freezing Rhubarb Crisp
For longer storage:
- Let the crisp cool completely.

Reheating Frozen Crisp:

Common Mistakes and Troubleshooting
Even experienced bakers can encounter issues when making Rhubarb Crisp. Here are common mistakes to avoid and how to fix them:
1. Watery Filling
❌ Rhubarb Crisp can become too runny if the fruit releases excess moisture.
✅ Solution: Add an extra tablespoon of cornstarch or flour to the filling. If using frozen rhubarb, be sure to thaw and drain it thoroughly before baking.
2. Overly Tart Flavor
❌ Too much tartness can overwhelm the dessert.
✅ Solution: Balance the flavor by adding more sugar or combining rhubarb with sweeter fruits like strawberries or apples.
3. Soggy Topping
❌ A mushy topping occurs when the crumble mixture is too wet or unevenly distributed.
✅ Solution: Use cold butter and ensure the mixture has a crumbly texture before baking. Spreading the topping evenly across the filling helps achieve a golden, crisp finish.
4. Burnt Edges
❌ Exposed rhubarb or uneven topping may burn before the filling is fully cooked.
✅ Solution: Cover the crisp loosely with foil if the topping is browning too quickly.
