Expert Tips for the Best Crisp Texture
A few small tips can make your Easy Rhubarb Crisp even better. So, keep these ideas in mind.
How to avoid a runny filling

Getting that perfect crumbly topping
Do not overmix the topping. Instead, keep it slightly chunky for better texture. Also, spread it evenly so it bakes consistently.
Adjusting sweetness to taste
Taste your rhubarb before mixing. Then, adjust the sugar level based on how tart it is. This helps you control the final flavor.
