Posta Negra (Colombian Black Beef)
Posta Negra (Colombian Black Beef)
Posta negra is a traditional Colombian dish of onion and garlic marinated beef roast braised in a cola/worcestershire sauce, giving it a dark color. This dish is always served with rice, fried plantains, and avocado.When choosing a beef roast for this recipe, you are going to want a leaner roast that is good for slicing. This goes against all of the rules of braising, where you typically would want a fattier cut such as chuck. Because the roast is marinated in the onions and garlic, the acidity of the onions acts as a tenderizer. So I recommend using either a sirloin tip roast, eye of round roast, or bottom round roast. While these roasts are served medium rare, this recipe has the cooked all the way through. It still turns out quite tender, plus the rich cola sauce will keep the meat moist.
