For the crépe dough, melt 50 g fat and let it cool down. Mix fat, flour, milk, egg, 1 tablespoon of sugar and salt to a smooth dough. Leave to rise for 30 minutes. In the meantime, peel, wash and cut the rhubarb into pieces. Mix starch and 4 tablespoons of apple juice. Boil up the rest of the juice and sugar, cinnamon and carved vanilla pod. Stir in the starch and bring to the boil briefly.
Add rhubarb and simmer for about 5 minutes. Let the compote cool down. Melt some fat in a small pan. Fry four thin pancakes from the crépe dough until golden brown. Fill with the compote. Dust with icing sugar and cinnamon
Decorate as desired with mint leaves
