Marinades can be made ahead and stored in the refrigerator for up to a week or more. When marinading, make sure the marinade covers the beef. Poke the beef with a fork to help the marinade infuse the beef. Marinating should be done in glass, plastic or stainless steel, never aluminum. Never reuse a marinade that comes in contact with raw meats. Place all marinating items in the refrigerator for the duration of the marinating time.
