When cooking fish, meat, poultry and vegetables, it can remove fishy smell and enhance flavor, especially in cold salad, which can not only enhance flavor, but also sterilize. Traditionally, people usually refer to "garlic" as garlic.
Garlic varieties can be divided into purple garlic and white garlic according to the color of bulb skin. Purple garlic cloves are few and large, with strong spicy taste and high yield. They are mostly distributed in North China, Northwest China and Northeast China, with weak cold tolerance, spring sowing and late ripening. There are two kinds of white garlic: large petals and small petals, which are less spicy and cold than purple garlic. It is sown in autumn and ripens earlier.
