Fruit-From-Your-Foodbox Crumble

My friend baked this today, roughly by following this recipe. Delicious! Looking forward to the cooler weather for some baking and roasting! It's also Halloween (and the same friend also carved the pumpkin!)!

Topping:
1/2 cup (65 grams) all purpose flour
1/4 cup (50 grams) granulated white sugar
1/4 cup (55 grams) light brown sugar
1/2 teaspoon ground cinnamon
1/4 teaspoon fresh or ground nutmeg (optional)
1/8 teaspoon salt
6 tablespoons (84 grams) cold unsalted butter, cut into pieces
1/3 cup (30 grams) old-fashioned rolled oats
1/3 cup (40 grams) chopped walnuts or pecans

Filling:
2-3 tablespoons (30 - 45 grams) light brown sugar
1/2 tablespoon cornstarch (corn flour)
1 1/2 pounds (680 grams) Granny Smith Apples or other firm, tart-tasting apple - peeled, cored, and sliced into 1 inch (2.5 cm) chunks
1 1/2 pounds (680 grams) ripe Bartlett or Anjou Pears, peeled, cored and cut into 1 inch (2.5 cm) chunks
1 cup fresh or frozen raspberries and/or strawberries

Apple Crisp: Preheat oven to 375 degrees F (190 degrees C) and place rack in the center of the oven. Butter or spray with a cooking spray, a 9 inch (23 cm) deep dish pie plate or an 8 x 8 x 2 inch (20 x 20 x 5 cm) baking dish. (Can also make 8 individual ramekins.) Set aside.

For Topping: Place all the topping ingredients (flour, sugars, spices, butter, oats and nuts) in a food processor and process until the mixture is crumbly (looks like coarse meal) and there are no large pieces of butter visible. (This can also be done with two knives or your fingertips.) Set aside while you prepare the filling.

For Filling: In a large bowl combine the sugar and cornstarch (corn flour). Peel, core, and slice the apples and pears and toss them, along with the berries, in the sugar mixture. Once thoroughly combined transfer to the prepared baking dish. Spread the topping evenly over the fruit.

Bake for approximately 35-45 minutes or until bubbly and the topping is golden brown and crisp. Remove from oven and place on a wire rack to cool for at least 15 minutes before serving. Serve with softly whipped cream or vanilla ice cream. Refrigerate leftovers and reheat before serving.

Makes about 6 servings.
