Ingredients:
- 3 cups (450g) fresh mulberries, rinsed and patted dry
- 3 cups (400g) rhubarb, cut into ½-inch pieces
- ¾ cup (150g) granulated sugar
- 2 tbsp (16g) cornstarch
- 1 tbsp (15ml) fresh lemon juice
- ¼ tsp (1.5g) salt
- 1 cup (90g) old-fashioned rolled oats
- 1 cup (120g) all-purpose flour
- ¾ cup (150g) packed light brown sugar
- ½ cup (115g) unsalted butter, cold and cubed
- 1 tsp (2g) ground cinnamon
- ½ tsp (3g) salt
Instructions:
- Preheat your oven to 375°F (190°C) and lightly grease a 9x9 inch baking dish.
- In a large bowl, combine the prepared mulberries and rhubarb.
- Sprinkle the granulated sugar, cornstarch, lemon juice, and 1.5g salt over the fruit.
- Toss gently with a spatula until the fruit is evenly coated and the sugar has dissolved into a light syrup. Pour the mixture into the baking dish and spread it evenly.
- In a separate bowl, whisk together the oats, flour, brown sugar, cinnamon, and 3g salt.
- Add the cold, cubed butter. Use a pastry cutter or fingertips to rub the butter into the dry ingredients until the mixture looks like coarse wet sand with a few pea-sized lumps of butter remaining.
- Spoon the crumble over the fruit, distributing it evenly but leaving it loose.
- Place the dish on the center rack of the oven and bake for 40–45 minutes until the fruit juices are bubbling vigorously and the topping is golden brown.
