After cutting the beef, rinse it with clear water to remove the blood. Add salt, monosodium glutamate, pepper, cooking wine and baking soda. Stir well, add water, add water bit by bit, and stir the beef while adding water, so that the water can completely penetrate into the beef. Meat is very elastic when it is slippery. Finally, put starch or raw flour! Baking soda can destroy the fiber of meat, keep more water in the meat and make the meat tender and smooth.
