Beat the egg and salt with the whisk of the hand mixer until foamy. Sift the flour onto the egg. Sprinkle with ground almonds and mix well. Add milk and stir in. Let the dough swell for about 20 minutes. In the meantime peel oranges and grapefruit so that the white skin is completely removed. Remove the fillets with a sharp knife between the parting skins.
Squeeze the parting skins, collect the juice and mix with honey. Heat the fat in portions in a pan. Bake the dough in it to 4 - 6 crêpes and roll them up. Cut in half and serve in portions with fruit fillets and sauce. Halve the almonds. Decorate crêpes with almonds and mint strips and dust with icing sugar
