Apple, Pear and Cranberry Crisp

For the filling

• 1.5 pounds crisp, tart apples, such as Pink Lady (about 5 apples)
• 1 pound ripe pears, such as Bartlett (about 3 pears)
• 2 cups unsweetened cranberries, fresh or frozen
• 1/3 cup sugar
• 2 tablespoons flour
• 2 tablespoons lemon juice
• 1/2 teaspoon cinnamon
• 1/4 teaspoon ginger
• 1/4 teaspoon nutmeg

For the topping

• 2 cups old-fashioned oats
• 1 cup walnuts, coarsely chopped
• 1/2 cup sugar
• 1/2 cup flour
• 1 stick salted butter, cut into cubes
• 1 teaspoon cinnamon
• 1/2 teaspoon ginger
• 1/4 teaspoon nutmeg
• 1/4 teaspoon sea salt

1. Preheat oven to 375 degrees.
2. Core the apples and pears and cut into chunks. (I have never peeled fruit for a crisp, but if you'd prefer to, go ahead!)
3. In a large mixing bowl, toss the apples, pears and cranberries with the sugar, flour, lemon juice and spices. Pour fruit mixture into a large baking dish.
4. In another bowl, combine all of the ingredients with the butter and work the mixture with your fingers until crumbly. Spoon the mixture over the fruit.
5. Bake for about 45 minutes, until the topping is a lovely golden brown and the fruits are bubbling through. Allow to cool for 10 minutes before serving.
