Marinating is a terrific basic kitchen technique. Essentially, you can take any kind of meat, fish or seafood, or even vegetables or soy products, submerge them in a marinade, and you’ve turned a plain something into a great dinner. Marinades add flavor — what kind obviously depends on the ingredients and seasonings. You can make (or buy!) anything from a Mediterranean herb- and citrus-centered marinade to a ginger- and soy-based Asian marinade to an Indian, spice-infused yogurt marinade.
