1 Cut beef into inches, cut potatoes into pieces, cut onions into sections with a knife, crush hawthorn with the back of a knife, and put some codonopsis pilosula and Lycium barbarum casually.

The purpose of stewing beef with water for 5 minutes is to remove dirt on the surface of beef and blood inside (this process is fire).

3 change the soup pot, add water and other materials, then boil the water, add tomatoes and beef, add beer and white vinegar beer to make it fresh and tender ~ ~ white vinegar is used to remove fishy smell ~ meat is easy to rot, and stew it on low heat.

4 stew 1 hour or so ~ ~ Chopsticks can be cooked in beef, but it has not yet reached the rotten effect. Continue to stew, then add potatoes. Potatoes are cooked into mashed potatoes too early, so the meat must be cooked and added for 20 minutes ~ ~ Take out a small piece of fat beef ~ ~ Chopsticks can easily penetrate, but not yet. The lean meat of beef is the least perishable.

5 at this time, you can stew without covering the lid, which is convenient for collecting juice. Adding salt at this stage (adding meat and salt too early is not easy to rot! ) the beef is rotten, so you can put it out of the pot!

The soup is so thick that you can't see tomatoes, but the smell of tomatoes has penetrated into potatoes and beef. This soup is the most nutritious. Finally, don't forget to add coriander to improve the taste.
