A few hours beforehand, add the raisins with the apple juice or alcohol and a little cinnamon and let them steep.
Preheat the oven to 220 ° C top / bottom heat.
Roll out the tarte flambée batter (I still use the rolling pin to enlarge it). Dice the apples and, if necessary, drizzle with lemon juice to prevent them from turning brown. Stir the drained raisins with a little cinnamon and, if necessary, sugar into the vegan crème fraîche and spread on the dough base. Since the oat cuisine is quite liquid, we thicken it 15 minutes before use with 1 tablespoon of psyllium husks or chia seeds. Spread the apples with the chopped walnuts on the crème fraîche. If necessary, sprinkle with sugar and cinnamon.
Put in the middle of the oven for about 14 minutes.
