The most popular pepper sauce is Tomato Nanmi. Tomato Nanmi is made from small, sour tomato and hot pepper. The hot pepper will be first roasted till the skin becoming burnt slightly with a special fragrance. Then the pepper skin will be removed and some ingredients like wild coriander, fragrant nuts and some other condiments will be added to make sauce. If small crabs are added, such a Nanmi is also called Crab Nanmi.
