First heat the cooking oil to 60% to 70% heat (people who often cook should know that it is almost enough, so don't put your hand in to test it, hehe). Add pepper and pepper, do not simmer (about 10 second). Then put the beef in, and turn down the fire at the same time (otherwise the meat will dry, and I can't save you with the stove at home), but your red pepper works, don't doubt it. ) Add salt, a little water and monosodium glutamate or chicken essence (trace amount) (but don't add water and monosodium glutamate chicken essence if you use chicken soup or duck soup), and then stir fry over high heat (the stir fry time depends on your knife method, hehe, if you chop it with an axe, you don't have to stir fry directly. ). The above does not include personal preferences. Some people who want to eat black can also put soy sauce (strongly not recommended), and can increase or decrease seasonings such as salt, pepper and pepper according to their personal tastes. There is no need to use so much meat if one or two people eat it. Hehe, there must be some left.
