6 tablespoons (3 ounces) unsalted butter, cubed and chilled
Instructions
Preheat the oven to 350°F.
Add the plums, 1/4 cup granulated sugar, cornstarch, ginger, lemon juice, and a large pinch of salt to a large mixing bowl. Toss gently to coat. Adjust sugar and citrus juice to taste.
Transfer the mixture to a pie plate or 8-inch square baking dish.
In a medium-size bowl, whisk together the oats, almond meal, brown sugar, 1/4 cup granulated sugar, and 1/2 teaspoon kosher salt. Add the butter, and rub the mixture together with your fingers, like when making pie crust, until the butter is incorporated and the mixture has a crumbly texture.
Sprinkle the topping over the filling. Place the baking dish on a baking sheet (in case the filling bubbles over) and bake until the topping is dark golden brown and the fruit is bubbling, 45 minutes-1 hour.
Serve warm with whipped cream, ice cream, full-fat Greek yogurt, or creme fraiche.
Notes
Firmer plums will keep their shape better than super-juicy fruit. Store extra almond meal in your freezer in an air-tight bag as it protects against rancidity and will greatly improve shelf-life. If you'd rather not purchase almond meal, grind almonds until powdery in a food processor (don't go too far or you'll have almond butter).
