1. Preheat oven to 375°F. Chop apples into slices or bite-size pieces. In a bowl coat the apples with fresh lemon juice to prevent any discoloration.
2. In a large bowl, combine the flour, brown sugar, sugar, cinnamon, nutmeg, cardamon, oats, and salt.
3. Add the butter and walnuts to the flour-oatmeal mixture. Stir until the mixture resembles coarse sand. For me its easiest to use my fingers to combine the butter and oats.
4. Butter a deep baking pan. Place the apples on the bottom and gently pack the crisp mixture on top.
5. Bake for 35-40 minutes or until apples are cooked and topping has browned. Serve warm with a dollop of whipped cream.

Serves 8-10.
