I've been very greedy these days, so I made beef with sauce to eat! This recipe was made by [Sister Xiao Gao], and I have done it many times! Delicious every time! The secret recipe is: three sauces! Soy sauce, sweet noodle sauce, fermented bean curd. Soak the beef tendon in water for a while to remove the blood. Then pour in some soy sauce and put it in the refrigerator to marinate overnight. The next day, put the soy sauce and beef into the pot, add water to submerge more beef (because the beef will rise and become bigger), remove the blood foam after boiling, then add various spices, add three spoonfuls of Sweet noodle sauce (a spoon for ordinary meals), two pieces of fermented bean curd. After stirring evenly, I switched to the instant pot again. If you don't have it, just continue to cook it in a normal pot. For a normal pot, use medium and low heat, and keep the soup in a state where the soup is not boiling (the meat will disperse if it boils) and cook it. About an hour and a half to 2 hours, is to cook until the chopsticks can be inserted in the state. Instant pot, I used meat stew/medium, 40 minutes, naturally deflated, it's good! very delicious! Just eat it like this, or cold it, it's super delicious! However, it is recommended to put it in the refrigerator for one night and then eat it, the meat will be much firmer and not easy to disperse. The soup can be reserved for making beef noodles! I ate beef noodles two days in a row! very delicious!
