🧂 Ingredients
- 4 cups Fresh rhubarb(chopped into 1-inch pieces)
- 2 cups Fresh or frozen saskatoon berries
- 0.5 cup Granulated sugar(adjust to taste)
- 2 tbsp Cornstarch

👨🍳 Instructions
- 1
Preheat oven to 375°F (190°C). Lightly grease a 9-inch pie plate or an 8x8 inch baking dish.
💡 Tip: A glass dish allows you to monitor browning from the sides. - 2
In a large bowl, combine chopped rhubarb, saskatoon berries, granulated sugar, cornstarch, and lemon juice. Toss gently to coat the fruit evenly.
💡 Tip: If using frozen berries, do not thaw completely to prevent mushiness. - 3
Pour the fruit mixture into the prepared baking dish and spread evenly.
⏱️ 2 minutes - 4
In a separate medium bowl, whisk together flour, rolled oats, brown sugar, cinnamon, and salt.
⏱️ 2 minutes - 5
Add the cold, cubed butter to the dry ingredients. Use a pastry blender, your fingertips, or a fork to cut the butter into the mixture until it resembles coarse crumbs with some pea-sized pieces.
💡 Tip: Keeping the butter cold is key to a crisp crumble topping. - 6
Sprinkle the crumble topping evenly over the fruit mixture in the baking dish.
⏱️ 2 minutes - 7
Bake for 35-45 minutes, or until the topping is golden brown and the fruit filling is bubbly.
⏱️ 40 minutes💡 Tip: If the topping starts to brown too quickly, loosely tent the dish with foil. - 8
Let the crumble cool for at least 15-20 minutes before serving. This allows the filling to set.
⏱️ 20 minutes💡 Tip: Serve warm with vanilla ice cream or whipped cream.
