Marinade is a “sauce, typically made of oil, vinegar, spices, and herbs, in which meat, fish, or other food is soaked before cooking in order to flavor or soften it”. Port wine is not an ingredient I normally keep in the house, but I have marinated a pork tenderloin before so 7-18: Pork Tenderloin in Wine Sauce shouldn’t be too much of a challenge.
Meat that soaks in a marinade comes out tender and delicious. Cooking with this method requires more preparation time. Leave the meat in the refrigerator for up to 24 hours for maximum tenderness. The minimum marinating time I recommend is around 1 hour. When I prepared this recipe, I tried to make it in one night, so the meat marinated in the refrigerator for only 2 hours.
