I don’t have self-raising flour that is required in the topping for the Apple and Blackberry Kuchen. Can use regular flour? Thank you!
The crumble is made with self-raising flour and ground almonds (almond meal), as this helps to give a slight lift to the crumble. It is possible to use plain (all-purpose) flour instead, just mix it with ½ teaspoon of baking powder. Put the flour and baking powder together in a bowl and whisk with a fork to combine, before adding the almonds and cinnamon and continuing with the recipe.
