To prepare a traditional cranberry apple crisp recipe, first you need to gather your ingredients. First, you will need the following ingredients: Granny Smith apples, sugar, cinnamon, nutmeg, salt, and vanilla extract. You will also need butter, flour, cornstarch, baking powder and salt. If you don't have any of these ingredients on hand, use granulated sugar instead. Then, add the dry ingredients to the wet ingredients and stir to combine. Pour the mixture into the pie shell and bake in the oven for 35 to 40 minutes or until the filling is bubbly and the apples are tender.
