I am a chef, and I often fry rice noodles like this. How long cold water runs depends on the quality of rice noodles. For example, the second-grade rice noodle needs to be soaked in warm water 1 hour. Because the second-grade rice noodle is troublesome and the first-grade rice noodle is fine, it will be soaked in cold water for 3 hours. Soak well in advance to drain water, then add light soy sauce, pigment, salt, monosodium glutamate and a little pepper and mix well. ※. The taste should be in place at once. When the water is dry, you can fry shredded squid, shredded pork with onion and ginger, chopped coriander, chopped cabbage and carrots and eggs. When these are ready, you can fry them. Come on, add shredded squid, stir-fry until fragrant, and then pour it out. Saute shredded cabbage, shredded carrot and shredded squid. Stir-fry shredded pork, add the mixed rice flour, stir-fry until fragrant, then add coriander, and stir-fry until fragrant. This rice flour needs more oil. Q: What do you think of the business of fried rice noodles in the night market? Answer: It should be good. Very economical. You can cook some salted peanuts and salted edamame, mix some cold dishes such as cucumber and kelp, 13 sweet lobster and cook some spicy snails. Believe me, I wish you success.
