For the Jerusalem artichoke pancakes with apple curd cream, peel the Jerusalem artichoke tuber, grate coarsely and mix with onion cubes, 50 g sunflower seeds, flour and egg yolk. Season with pepper and salt.
Briefly roast the remaining sunflower seeds in a frying pan without fat, set aside.
Cut the apples into quarters and stone them. Finely dice one apple, sprinkle with 1 tablespoon lemon juice. Cut the second apple into thin slices, also sprinkle with 1 tablespoon lemon juice, then cover and set aside.
Blend the curd with the remaining lemon juice until smooth, then mix in the apple cubes. Refrigerate the apple curd.
Heat 1-2 tablespoons of oil in a large frying pan. Place one tablespoon at a time of the pancake mixture in the pan and spread apart a bit.

When serving, place three Jerusalem artichoke pancakes on each plate, place the apple curd in the center, top with apple pieces and sprinkle with toasted sunflower seeds.
