The most classic hamburger is beef hamburger, which contains tomatoes, lettuce and pickles. The sauces are tomato sauce and yogurt sauce. First, use a blender to grind half of the beef into powder, and the other half will be chopped into powder by hand, because it will be chewy. If you grind it all by machine, you will lose your chewing power. Drop the beef stuffing more than ten times to make the beef stuffing feel sticky, then add an egg to the beef stuffing (if you like onions, you can blanch them, then dice them and add them to the beef stuffing), then stir the beef and eggs evenly, and then make the beef stuffing into a beef pie with a thickness of 1cm, which is too thick to be cooked easily. Add oil to the pot, then add the beef patties and fry them on both sides until they feel burnt. If you are afraid that the inside is not cooked, you can put some water in the pot, then quickly cover the pot and steam the inside of the beef patties. After the steam disappears, fry for a while, and then take out the pot for use. Fry the bread a little, then blanch the tomatoes and lettuce for later use. Dice some pickles and add them to the yogurt sauce for later use. So you can start to shape the hamburger. Put a slice of bread first, then a slice of lettuce, then pickles, then yogurt sauce, then a slice of lettuce, then some tomatoes, then tomato sauce, then beef patties on tomatoes, and bread on beef patties, so a delicious hamburger is finished.
