  5. Bake at 350°F (175°C) for 12 to 15 minutes.

Tips & Substitutions

For a delightful twist, consider adding a pinch of cinnamon or nutmeg to the fruit mixture for extra warmth. If you don't have margarine, unsalted butter works well too. For a gluten-free option, substitute all-purpose flour with a gluten-free blend. Make sure to wash the blueberries thoroughly before using to remove any dirt or residues.

Serving Suggestions

Serve this crumble warm with a scoop of vanilla ice cream or a dollop of whipped cream on top for a decadent dessert. It pairs beautifully with a refreshing glass of Holiday Banana Punch for a delightful meal experience. For breakfast, enjoy it plain or with yogurt for a healthy start.

Storage & Reheating

Store any leftover crumble in an airtight container in the refrigerator for up to 3 days. To reheat, place individual portions in the microwave for 30-60 seconds or warm the entire dish in a 350°F (175°C) oven for about 10-15 minutes until heated through. This keeps the topping crispy.

Frequently Asked Questions

Can I use frozen blueberries or rhubarb for this recipe?

Yes, you can use frozen blueberries and rhubarb, but be aware that they may release more moisture during baking. It's best to thaw and drain them before adding to the mixture to maintain the crumble's texture.

How do I know when the crumble is done baking?

The crumble is done when the topping is golden brown and the fruit is bubbly. You can insert a toothpick into the topping; if it comes out clean, it's ready. Keep an eye on it to avoid over-baking.

Can I make this crumble ahead of time?

Absolutely! You can prepare the crumble topping and fruit mixture separately in advance. Assemble and bake it the day you plan to serve it for the best texture. Alternatively, you can bake it ahead and reheat as needed.
