                                                          You can find commercial tenderizers such as Adolph's on the spice shelf but for a more natural way try marinating in anything with an acid or wine base. A combination of red wine or red vinegar, lemon juice, garlic,bay leaf and salt and pepper can do wonders. Mix it up, spread over the meat, cover. Refrigerate one hour.
