Top Tips for Perfecting Your Rhubarb Crunch
- Ingredient Substitutions: If you’re not a fan of oats, feel free to substitute them with crushed nuts for added texture.
- Don’t Skimp on Spices: A pinch of nutmeg alongside the cinnamon can add a fragrant warmth.
- Timing is Everything: Keep an eye on the crunch topping to prevent it from burning. If it browns too quickly, tent it with foil.
- Rhubarb Prep: Be sure to wash your rhubarb and trim the ends before dicing, as this will keep the taste fresh and sweet.
Storing and Reheating Tips
Leftover Rhubarb Crunch can last in the refrigerator for up to 5 days when stored in an airtight container. If you want to keep it longer, you can freeze portions for up to 3 months. To reheat, simply place in the oven at 350°F (175°C) until warmed throughout or microwave it for a quick fix. Just be sure to top it with a little cold ice cream to make it extra delicious again!
FAQs
