Brandy Marinade
1/3 Cup Brandy, bourbon whiskey or beef broth
1/3 cup soy
2 Tablespoons packed brown sugar
2 Tablespoons of vegetable oil
½ teaspoon of pepper
1 small onion, chopped (about ¼ cup)
1 clove of garlic, finely chopped
Mix all ingredients in a shallow glass or plastic dish. Place meat in dish and turn to coat all side with the marinade. Cover and refrigerate at least 24 hours, turning meat occasionally. I like to put it in a ziplock bag overnight.
Double all measurements if you have a lot of steak.
