The best marinade has three basic components: an acid, oil, and your favorite flavorings. Within this basic formula, you can really go wild with flavor. For an acidic ingredient, I like to use vinegar, fresh citrus juice, or even wine! Use a neutral oil, like olive or avocado, and feel free to load up on flavorings. Ingredients like Worcestershire sauce and soy sauce can add intensely savory flavors with minimal effort, so they're common in marinades. I also love to add fresh or dried herbs, mustard, honey or maple syrup, and spices. Each of these simple steak marinades is tested to have just the right balance of all these three components, so you can use them and go!
