How to prepare pig intestines:

Clean. A pair of large intestines, washed according to the above method. Blanch. Place the entire large intestine in a pot under cold water, add white wine to the onion and ginger slices, boil for 5 minutes, turn off the heat, take it out, and rinse with cold water until it reaches natural temperature. The key to this step is that white wine, green onions and ginger are powerful tools for removing odors. Blanching and rinsing with cold water is to increase the taste of the large intestine and make the finished dish crisp and tender. Boil in water until mature. Still onion, ginger, white wine, add dark soy sauce, and cook the large intestine for 30 minutes. Why use white wine or high-quality white wine? Because pure high-strength grain wine is the best at removing unpleasant odors, restaurants are reluctant to use it, so their recipes all use cooking wine. Take out the cooked intestines, cut them into inch-inch sections, and then use the intestine section at the head of the intestine as the basic unit. Stuff other parts of the intestine into the head section of the large intestine so that no gaps are left. This process is the key to getting a crispy texture on the outside and tender on the inside. Why? See below. Heat the oil in the wok until it is 60% hot and slightly smokey. Add the decorated large intestine section. The oil surface covers about half of the large intestine section. Fry and fry until the outer layer of the large intestine section feels burnt when touched with a shovel. Remove it and set aside. In a separate wok, sauté the minced onion, ginger, and garlic, add vinegar to release the flavor, add dark soy sauce, enlarge the intestines, and cover with broth. Keep the fire on high to keep the juice in the state. When the juice is reduced to less than half, scoop out the large intestine segments and put them on a plate. Boil the soup in the pot until thick and pour it over the large intestine segments. If you want it to look better, burn a spoonful of Sichuan peppercorn oil and pour it on. The oil will be bright in color.
