Prepare the Meatball Mixture: Mix the minced meat, egg, finely chopped onions, potato flour, cream, salt, MSG (optional), black pepper, and turmeric together. Let the mixture rest in the refrigerator for 30 minutes.
Poach the Meatballs: Bring about 1 liter of water with a little salt to a boil. Form the meat mixture into small balls and poach them in the boiling water until they are cooked through. Remove the meatballs and set aside.
Prepare the Curry Sauce: In a pot, bring the cooking liquid or bouillon to a boil. Add the toasted curry powder and cream, and let it simmer. Thicken the sauce with cornstarch dissolved in water. Season with salt and pepper to taste.
Serve: Serve the meatballs in the curry sauce with cooked rice. Optionally, add toppings like fresh parsley, chutney, or toasted nuts.
