Cook the rice first. It can be prepared in advance and stored in the refrigerator. To do this, rinse the rice in cold water, let the water drain and put it in a deep frying pan. Mix the rice well with the vegetable oil. Then add salt (to taste) and water in a ratio of 1:2 (take 2 cups of water for a glass of rice). Close the lid and cook over low heat until the water has completely evaporated.
