Cook the rice until it is firm to the bite. Then take it out of the bag. Let cool and mix in a bowl with the raw minced meat, egg, ajvar, crushed garlic and half a finely diced onion. Season to taste with salt, black pepper, paprika and coriander and mix again.
Now shape the mixture into balls the size of a table tennis ball and refrigerate for 15 minutes.
Meanwhile, boil 2 liters of water in a large saucepan with the appropriate amount of meat stock (instant or cubed). Cut the remaining 1 1/2 onions into strips and the peppers into 2 cm x 2 cm cubes. Pour into the boiling pot and cook for about 5 minutes until soft.
Take the saucepan off the stove and put the meatballs in the fridge. You can lie on top of each other because they have become firm enough through the cold setting. Simmer on the stove for about 20 minutes on medium heat. When they are done (spot checks are recommended), they should be removed individually if possible so that as much of the vegetables as possible remain in the pot. Keep the balls covered and warm. Processed cheese, crème fraîche, ajvar and spices can now be added to the broth as desired. The sauce should definitely be creamy.
To thicken the sauce, add flour or cornstarch (dissolve in warm water beforehand so that no lumps are formed) and bring to the boil again until the desired consistency is achieved.
Now add the meatballs to the sauce and serve with pasta or potatoes.
