apple crumble topping
Fragrant Apple Filling
Apples are obviously the essential components. You can make use of cooking apples (or apples for baking), but truthfully, any kind will certainly work as long as you are OK with either a mushier or chunkier apple part. Also, if you pick tangy apple, you may need to add more sugar to balance the slightly sour flavor. But when I use sweet apples, I often entirely leave out the sugar in the apple mixture.
However, cinnamon for me is a necessary element in the apple part of the crumble. One tsp ground cinnamon makes certain the dessert (as well as your whole house!) will scent lovely. You can also add some cloves to your apple treat for some additional flavor.
