Cut the onion into thin feathers, heat the oil in a deep bowl and fry the onion on it until golden brown. I cut the tomato in half, removed the tail and grated the pulp to the skin. Add the resulting tomato mass to the onion, a pinch of sugar and let it warm up together for 2 minutes. Then add all the spices, salt and crushed garlic, pour in a glass of boiling water, cover with a lid and cook over low heat for 10-15 minutes.
