Place the potato pancakes on a baking tray and bake in a preheated oven (electric cooker: 200°C/ gas: level 3) for 20-25 minutes. Peel garlic and press it through a garlic press. Peel onion and chop very finely. Mix salad cream and yoghurt. Stir in onions and garlic and season with salt and pepper.
Mix in dill. Pour shrimps on a sieve, rinse with cold water and dab dry with kitchen paper. Fold half the shrimps into the yoghurt salad cream. Arrange 2-3 potato pancakes on each plate, pour some yoghurt salad cream over the pancakes and sprinkle the remaining shrimps on top. Arrange on a salad leaf as desired, garnish with lemon wedge and dill
