Yes, marinating raw mutton before freezing is a great way to enhance its flavor and tenderize the meat. The marinade will penetrate the meat during the freezing and thawing process.
Marinating mutton before freezing offers several advantages. Firstly, the marinade's acids, such as vinegar or lemon juice, help to break down the tough muscle fibers, resulting in a more tender final product. Secondly, the flavors of the marinade infuse the mutton, leading to a richer and more complex taste after cooking. Thirdly, the freezing process itself aids in the penetration of the marinade, as the expansion of water during freezing helps to carry the flavors deeper into the meat.To marinate mutton before freezing, prepare your marinade as usual. Submerge the mutton pieces completely in the marinade, ensuring all surfaces are covered. Place the marinated mutton in a freezer-safe bag or container, removing as much air as possible to prevent freezer burn. Label the container with the date and contents. When you're ready to cook the mutton, thaw it in the refrigerator. The thawing process will also allow the marinade to continue working its magic.
Avoid using too much salt in your marinade if you plan to freeze the mutton for an extended period. Salt can draw out moisture from the meat, potentially leading to a tougher texture after thawing. Consider adding more salt during the cooking process instead.
