I know the recipe is a bit vague, but the meal is decidedly delicious. I'm in Brazil now and this is the way they do things - relaxed. Use your creative flare to decide what "tender beef" means and how big a "small carton" is. I put in extra tomato sauce and was very happy with it.
2 pounds of tender beef
1 TBS of butter or margarine
1 pinch of black pepper
1 pinch of oregano
1 pinch of rosemary
1 tsp of salt
1 TBS of Worcestershire sauce
1 small carton of heavy cream
1 jar of mushrooms
1 diced onion
1 diced tomato
5 tsp of ketchup
1 small can of tomato sauce
1 jar of palm hearts, diced
Clean the beef, cutting off all fat and slice into small pieces. Spice with salt, pepper, oregano, and rosemary. Melt the butter and brown the meat. Add the onion, tomato, and Worcestershire sauce. Mix well then add ketchup, tomato sauce and 1 cup of water. Cook over medium heat for 10 minutes. Add mushrooms and palm hearts. Finally, add the heavy cream and simmer for 15 minutes.
Best served over rice with shoestring potatoes.
