Preparation
Boil the Beef
Place the beef in a large saucepan with enough water to cover it.
Bring the meat to a boil, cover and simmer for 2 hours.
Remove from the heat and leave and allow to cool.
Set aside the water.
Shred the beef into strands with a knife or meat rake (or two forks) until all the beef is shredded.
Make the Sofrito
Chop and dice the onion and bell pepper.
Crush the garlic in a pestle and mortar or in a garlic crusher (mince fine and then crush with the blade of your knife with salt)
Preparing the Dish
Heat 4 teaspoons olive oil in a large frying pan. Add the onions and allow them to start to brown. Then add your garlic, bell peppers, a pitch of salt, black pepper and the cumin.
Add the shredded beef and stir, allow to brown a little.
Add some of the beef cooking liquid, the tomato puree and a dash of Worcestershire sauce.
Stir frequently as you bring the mixture to a boil, then lower the temp to a simmer and allow to cook for 15 minutes.
Serve with rice and beans or make a sandwich and serve it in an Arepa.
