Caramelise 2 tablespoons of sugar in a frying pan. Add almonds and butter. Brown the almonds while stirring. Spread on a lightly oiled plate and let cool off.
Peel oranges and grapefruit so that the white skin is completely removed. Cut out the fillets between the parting skins. Mix with liqueur and icing sugar.
Grease a pan (approx. 20 cm Ø) with a little oil. Bake approx. 12 golden brown crêpes one after the other from the dough. Keep warm. Arrange the crêpes with citrus fruits and almonds. Serve with vanilla ice cream or cream.
