Cut the fruit flesh into small pieces. Steam with 4 tablespoons lemon juice and 3 tablespoons water in a closed pot for about 10 minutes.
Season to taste with 4 tbsp. sugar and crush finely with a hand blender. Let the finished applesauce cool down, then put it in a cool place.

Mix flour and baking powder, alternately stir in with the natural yoghurt. Fold in grated apple. Preheat waffle iron and grease lightly.
