A good steak marinade....I use it for beef or venison....I don't measure, so you may want to add more or less of each ingredient depending on taste:
Worchester Sauce 2-3 tablespoons
Soy Sauce 1 tablespoon
Garlic Powder 1/2 teaspoon (or you can use fresh)
Steak Sauce - any brand sweet&spicey 2 tablespoons
Lemon Juice 3-4 tablespoons
Mix first 4 ingredients first, then stir in lemon juice. This makes enough to coat 2 large Delemonico steaks. You can lay them in a glass dish or SS pan or use a ziploc bag. Marinade a few hours or over night. Grill or pan fry.
