Prepare the brine. Pour sugar and salt into an enameled bowl. Pour 0.5 liters of boiling water from a kettle, mix, put on fire, pour in sunflower oil and vinegar. Bring to a boil and pour over the cabbage. Cabbage is compacted, and it is easier to pour water into it using a long-handled spoon or fork. Gradually pour in the water and use a spoon to pierce the cabbage layer to the very bottom. It will take the whole pint of brine, well, if a little remains. My photo shows that there are a couple of tablespoons of brine. Cover with a plastic lid and transfer to a plate to cool. I cook such cabbage in the evening, in the morning it is ready for use.
