How to Make It
Preheat the oven to 375° and set a rack in the bottom third. Place the apricots in a shallow 2 1/2-quart baking dish, such as a 10-inch round dish.
In a food processor, grind the almonds with 1/4 cup of the brown sugar until fine, about 30 seconds. Add the lemon zest and process for 5 to 10 seconds. Scrape the sugar mixture over the apricots and toss. Scatter the raspberries and blueberries over the apricots and drizzle with the lemon juice.
In the food processor, combine the flour, cinnamon, salt, oats and the remaining 3/4 cup of light brown sugar; process for 10 seconds. Add the butter and pulse just until the mixture resembles coarse crumbs. Sprinkle the topping evenly over the fruit and bake for 55 minutes, or until the topping is browned and the filling is bubbling. Let the crumble cool on a wire rack and serve.
