Sweet and Sour Braised Beef Shank

Method

1. 1 Cut the beef into 4 cm cubes, then marinate with fish sauce and chopped onions for 30 minutes.
2. 2 Pan-fry the beef block for 5 minutes until the outside is dark brown.
3. 3 Sauté the chopped tomatoes for 6 minutes until they dissolve into a sauce, then add just enough water to cover them.
4. 4 Simmer over low heat for 70 minutes, but do not add the vinegar to the pot yet.
5. 5 Adding vinegar from the beginning is an acid that makes the meat tough and prevents it from becoming tender even after prolonged cooking.
6. 6 Add vinegar, sugar, and carrots during the last 20 minutes, then simmer until reduced and sprinkle with chili and green onions.
