Salt and pepper are a spicy condiment. Salt-and-pepper method: stir-fry the white pepper particles to smell and grind them into powder. Red dried pepper is ground into powder, and a little monosodium glutamate is ground into powder. Grind refined salt into powder, fry it in a pot, and then fry it with the three powders to get salt and pepper. If it's spicy, add more pepper and red pepper powder. (the proportion can be according to your own requirements)
