Season the beef with a generous amount of salt and pepper, then sear on high heat for 7 to 10 minutes.

Turn the heat down to medium-high, then add a tablespoon of oil to the pot. Once the oil is hot, add the carrots and onions and fry for 5 to 7 minutes.

Add the worcestershire sauce, mustard, beef cube, and 3 to 4 cups of water. Simmer until the beef is tender.
