How to Perfect Best Rhubarb Crisp
To ensure your Best Rhubarb Crisp turns out perfectly every time, follow these simple tips.

- Adjust Sweetness: Depending on your taste preference, you can adjust the sugar in the filling. Taste the rhubarb before adding sugar.
- Don’t Overmix Topping: Mix the streusel topping just until combined for a crunchy texture. Overmixing can lead to a dense topping.
- Bake Until Bubbling: Ensure you bake until the filling is bubbling around the edges; this indicates it’s cooked through.
- Let It Cool Slightly: Allow the crisp to sit for about 10 minutes after baking. This helps set the filling for easier serving.
- Experiment with Spices: Feel free to add nutmeg or ginger for an extra layer of flavor in the filling or topping.
