Mix sea buckthorn, 1 tablespoon lemon juice and apple juice and bring to the boil. Mix cornflour in a little water and thicken the sauce with it, bring to the boil again and let it cool down. Separate the eggs. Stir egg yolk, milk, flour, salt and baking powder until smooth. Wash, quarter and core apples.
Cut quarters into slices. Sprinkle with 2 tablespoons of lemon juice. Beat egg whites until stiff and fold into the dough. Heat the oil in portions in a small pan (approx. 15 cm Ø). Place 1/4 of the apple slices in the pan and pour 1/4 of the pancake batter over them. Fry over medium heat for 3-5 minutes on each side. Bake the rest of the apples and dough in the same way. Whip the cream until stiff. Arrange pancakes, cream and sea buckthorn sauce on plates.
