1. When boiling beef in clear water, prepare 800g fresh beef, wash it, cut it into large pieces with a knife, then put it into a basin, add enough clear water to soak it for three hours, and change the water 2 to 3 times during the soaking process. Finally, pour out all the blood and rinse it with clear water.

2. Put enough cold water into the pot, then put the beef cold water into the pot, cover the pot and heat it until it boils, and remove all the floating foam on the water surface. When there is no foam in the pot, you can add a proper amount of onion ginger and dried hawthorn, and then cook for an hour on low heat. At this time, the beef in the pot can be cooked thoroughly, and the taste is particularly soft and rotten, so you can eat it when you take it out.
