For the dip, cut the grenadilla in half and scrape out the pulp with a spoon. Mix yoghurt, salad cream, milk and grenadilla pulp. Season with 1 teaspoon curry, salt, pepper and 1 pinch of sugar.
Cover and place in a cool place.
Soak rolls in cold water. Wash parsley, shake dry, pluck off leaves and chop finely. Peel onion and chop finely. Knead minced meat, onion, squeezed bread roll, parsley and egg.
Season with salt, pepper and Sambal Oelek (according to taste).
Form approx. 20 balls from the chopping mass with moistened hands. Heat the oil in a large pan. Fry the meatballs in it in portions all around for 7-8 minutes. Serve the meatballs hot or cold with the grenadilla dip.
