You start with the production of the meatballs, for which the minced meat is mixed with an egg, salt, pepper, oregano and basil. Shape it into walnut-sized balls and fry them well in a little olive oil in a hot pan. Continue frying on a lower flame for about 5 minutes (even if the balls look very soft at the beginning, they are just right in the sauce!).
Now put the tomatoes in the pan and dilute with a little water. Season the contents of the pan with the broth (a good 3 tablespoons), salt, pepper, herbs and a little sugar. Stir in the sour cream and simmer for 10 minutes. During this time, cook the pasta in salted water as usual.
