Peel apples and pears and cut into small pieces. Bring the water, vanilla sugar, lemon zest, cinnamon and lemon juice to the boil, add the fruit. Cover and steam for approx. 5 minutes (depending on the size of the pieces).
Pour off the water and pass the pieces through the mill while they are still hot or mash them with the potato masher.
We like the puree best lukewarm with vanilla yoghurt or natural quark or, for example, with steamed noodles or pancakes.
Tip for those in a hurry: Cook the fruit unpeeled and eat it as apple pieces instead of processing into puree.
