Apple Rhubarb Crisp with Lemon

Instructions:

1. In a large bowl, combine the cubed apples and rhubarb.
2. Drizzle in the lemon juice, then sprinkle with sugar, flour, cinnamon, and salt.
3. Stir gently until the fruit is evenly coated in the flour mixture.
4. Pour the mixture into a 9x9 inch baking dish, spreading it into an even layer.
5. In a clean bowl, whisk together oats, flour, brown sugar, cinnamon, and salt.
6. Add the cold, cubed butter. Use a pastry cutter or your fingertips to rub the butter into the flour until the mixture resembles large, pea-sized breadcrumbs.
7. Gently squeeze a few handfuls of the mixture to create larger clumps.
8. Scatter the oat mixture evenly over the fruit, leaving a few large clumps intact for texture.
9. Bake at 375°F (190°C) for 40–45 minutes until the topping is golden brown.
