1. Cook the vermicelli for 30 seconds to three minutes.

2. The texture of vermicelli is different, and the cooking time will be different. For thinner vermicelli, just boil it in hot water for about 30 seconds. For thicker vermicelli, you need to increase the cooking time as appropriate. The time of cooking the vermicelli should not be too long, so as not to affect the taste of the vermicelli. The cooked vermicelli needs to be immersed in cold water before being used for cold dressing, so as to prevent the vermicelli from sticking.
