You don't need chicken essence. Chicken essence is 91% monosodium glutamate, but with some spices, people can increase their appetite and strengthen their physique. But the real soup of crossing the bridge rice noodles is made of old chicken (chicken over one year old), which is hard to master and has a bad smell. The main reason is that the chicken should be washed, and the chef's method is to blanch the water. My method is to give the chicken a bath. (Just like giving a person a bath, a chicken for one year should be able to rub off the mud, just like a demon eating Tang Priest and giving Tang Priest a bath.) Small chicken skin is tender and can't be rubbed, so it doesn't taste good, so it can't be used. Clean chicken can only be cooked with water and salt for 41 minutes (I exaggerate, in fact, I can add pepper aniseed without adding it), and the aroma will be overflowing. Neighbors can know that friends love it, so they advised me to open a shop. I can't sell it myself, and I won't make any money by selling a bowl of 15 yuan. (It's mainly because it's too labor-consuming, not a matter of materials) So I haven't opened a shop, so I'll teach you the secret for free, and I'll try it if I don't bother. There is also a set of fish I cook, which needs to be washed just like chicken, and the washed fish is not sticky (generally, it needs to be washed with water for three times, but the fish needs reservoir fish and river fish (unpolluted rivers). Don't dirty water fish, and the dirty water fish will smell fishy if washed again, and it needs to be spicy and hemp to suppress it. Clean fish only need water and salt to cook for 21 minutes (I exaggerate, in fact, I can add pepper aniseed without adding it), and the fragrance will be overflowing. My two dishes have the same requirements, but it is not easy for ordinary restaurants to do it, but you should do business with conscience, take the trouble and ignore the cost, you can try it, and remember me when you make a fortune.
