For The Apples For The Crumble Topping

1. Preheat the oven to 190°C.
2. To make the topping, in a medium bowl, combine the flour, white sugar, brown sugar, cinnamon, salt, and ginger if using. Add the cold butter and use a pastry cutter to cut in butter until the mixture starts to stick together and form crumbs the size of large peas, about 3 to 4 minutes. Place in the fridge while preparing the apples.
3. Place the sliced apples in a 2qt baking dish and toss with the sugar, flour, and cinnamon.
4. Sprinkle the prepared crumble topping over the apple mixture. Bake uncovered for 35-40 minutes or until golden and the apples are soft.
5. Serve warm or room temperature with vanilla ice cream if desired.
