For the apple compote, peel, quarter, core and cut apples into pieces. Boil up with apple juice, cinnamon and sugar in a pot while stirring. Simmer at medium heat stirring several times for about 20 minutes. Let it cool down
Peel, wash and finely grate (do not grate!) the potatoes. Drain the potato puree in a sieve, collecting the potato water in a bowl. Peel and grate the onion. Mix with the grated potatoes. Drain the potato water and add the potato flour to the potatoes. Add eggs, flour and salt, mix well
Grease the waffle iron and bake about 4 waffles one after the other from the dough. Serve still hot with apple compote. Maple syrup tastes good with it
