# Wash the
rice and strain it. Then, put it into a small pot. Add 5 cups cold water on it, and place the pot over low heat.
# Cook it until the
rice soaks the water totally.
# Remove it from the stove and let it cool down.
# Put ground meat, boiled and cooled down
rice, salt and black
pepper into a deep mixing bowl.
# Add crumbs in it during the kneading, until the mixture reaches to the right consistency (about 5 minutes). It must not stick to your hands.
# Pick pieces, which are smaller than
walnuts, from the kneaded mixture and shape them into patties. Place these patties onto a large plate. Then, place this plate onto the lowest layer of the fridge to refrigerate them for half an hour.
# Then fry the meatballs with some oil.
# Put vegetable oil into a separate pot and make it hot over medium heat. Then, add quarter circle shaped sliced
onion in it and fry them.
# When the
onion turns into yellow, add
tomato paste and salt in it. Sauté this mixture, until the smell of the paste goes away.
# Add water on it. When the water mixture reaches to the boiling temperature, add the fried meatballs in it and cook the mixture for about 10 more minutes.
# Finally add the vinegar in it and stir the mixture without losing the shapes of the meatballs. 2 minutes later, remove the pot from the mixture.
# Serve it hot.
