They are all processed by themselves, but the sauce and packaging are delivered by the company. A packet 12 cent, a catty of 6 yuan sauce. Freight pays. Salt water should be processed and produced by itself. Delicious braised pork, spicy tripe, thousands of venetian blinds and crispy lotus root are all made of this brine. Ham and chicken fillet should be fried by themselves, and eggs should be fried by themselves. It's actually quite simple. It's not as complicated as you think. I joined right after graduation, and I can't even cook at ordinary times. In fact, you can make it by looking at the menu, but at first it was unskilled and slow, and the rolled cakes were not round and uneven in thickness. As long as you do more, it will be all right soon. I joined your brother last year and made it in Shenzhen. Now I don't do it anymore. I can transfer my technology, bread, brine and sauce (note: the sauce formula was obtained from special channels, and everything else was learned when I joined), so I can teach you at a cheaper price. You can taste my cooking first, and then teach it when you feel authentic. Learn to give again. I have contact information in my file.
