Preparation: Set the wok on fire and burn it very hot. Then put the bought pig's trotters (chopped into small pieces in the supermarket) in the wok to get smoke (the cooked pig's trotters don't smell when eaten), take them out and wash them, and then fly them in boiling water for later use.

Ingredients: ginger, pepper, dried pepper, three-star anise, Pixian watercress, sugar, grass, fragrant leaves, cooking wine, soy sauce, chicken essence, salt, chopped green onion and so on.

Practice: You can make spicy or non-spicy oil according to your preference, add white sugar and stir-fry under a little heat, then add ginger and stir-fry until it is fragrant, then add Pixian watercress and continue to stir-fry until it is fragrant. At this time, pour in the cleaned trotters and stir-fry for one minute, then pour in soy sauce. The cooking wine will continue to stir-fry until the trotters in the pot are lusty and shiny, and add the spices prepared above one after another. Note; Chicken essence, salt and chopped green onion should be added when the pig's trotters are cooked. It tastes more delicious that way.

How to cook pig's feet in a pressure cooker: pour the fried pig's feet into the pressure cooker, and inject both hot and cold water, but the water should just flood the pig's feet in the pot. Cook them with strong fire until they boil, and then slowly cook them with low fire 18 minutes. Note: too little water will burn the pig's feet, and too much water will not taste good, and the pig's feet will melt if they are cooked for too long. Add salt when taking out of the pot. Stir-fry the chicken essence for a few times, and serve.
