The Maçarico Vinha d'Alho marinade is a traditional Portuguese marinade made from red wine vinegar, garlic, and spices. It is commonly used to marinate red and white meats, as well as poultry. The acidity from the vinegar and the pungent taste of garlic and spices work together to help tenderize the meats and add a unique and delicious flavor. This marinade is a great way to enhance the taste of any meat dish and is perfect for grilling or barbecuing.
