Use beef tendon meat. When you buy it, just say calf tendon. Take it back and marinate it with salt, sugar and monosodium glutamate. After one hour, add soy sauce to color it and marinate it for more than 8 hours. Stir-fry rapeseed oil (rapeseed oil fragrance) for sauce, then fry the oil with shallots, coriander, ginger, garlic seeds, cinnamon, star anise, fragrant leaves, angelica dahurica, cardamom and kaempferia kaempferia, then add water, and pour in the water for curing meat. Cook together for about 2 hours, and then simmer. It is estimated that when cooked, turn off the fire and soak for an hour before eating. It tastes good and smells enough! The taste of salt is controlled by yourself, so the water tastes a little salty.
