Acidic vinegar and onions used to complement a rich cut of beef is typical for Central American cuisine. This marinade features a traditional Puerto Rico/Dominican Republic steak and sauce with onions. Sirloin flap can vary in thickness, so cooking times can differ depending on which part you get. Use a pan that has a lid, as cast iron is not recommended due to the high acidity.
