First, peel the potatoes and cut them into strips, as shown in the figure below. When we buy potatoes, we'd better not choose potatoes with green skin or buds, because such potatoes are easy to be poisoned.

Second, then put a proper amount of cooking oil in the pot, pour in potatoes and fry them for ten minutes, then take them out and drain them.

Third, cut the pork belly into thin slices and fry it in the pot for 3 minutes, as shown in the figure below. When we cut the pork belly, in order to ensure that each piece of pork belly is very thin, we can put the pork belly in the freezer for ten minutes first, and then take it out and cut it, which will be easier.

Fourthly, cut the garlic into minced garlic, cut the pepper into pepper foam, and pour it into the pot for frying, as shown in the figure below. When frying garlic and pepper, you must turn on a small fire, otherwise garlic and pepper may splash out and hurt your skin. We must pay attention to this.

Fifth, then pour the potatoes into the pot and stir fry for three minutes, as shown below.

Sixth, then add a proper amount of white rice vinegar to the pot and stir fry for two minutes.

Seventh, then add a proper amount of salt and monosodium glutamate to the pot, stir-fry for a while and you can get out of the pot.

Eighth, a delicious fried pork with hot and sour potato shreds is ready. I hope you like it.
