Marinades: making your own marinades is just needing to mix up an Acid, an Oil, and seasonings.
Acids are the part that tenderize the meat. This can be things like vinegar, buttermilk, lemon juice, pineapple juice, teriyaki or soy sauce, etc...
Oils should be chosen for flavor, but also for the cooking method. Make sure the oil can handle the temp you'll be cooking at without smoking/scorching.
Seasonings are complementary flavors to your acid and oil to enhance the complete package.
