Wash the tender stems and leaves of gray vegetables (because there is silver powder on the surface of gray vegetables, you can wash them several times).
Second step
Add a proper amount of flour and stir well until all leaves are covered with flour (you can also add an egg if you like), and steam in a steamer (about ten minutes after the pot is boiled).
Third step
Put the steamed grey vegetables in a pot, add salt, garlic paste, spiced powder and vinegar, and finally pour boiling cooking oil on the seasoning, and a pot of steamed grey vegetables will be fine.
