The Jaccard 45 Blade Removable Cartridge Meat Tenderizer features 45 razor sharp high strength stainless steel blades, ideal to make any cut of meat tender, including chicken, beef, pork, veal, duck, fish, steaks, roasts, whole turkeys, and more. This process reduces cooking time by 40% and significantly enhances the speed and penetration of marinades and rubs. It also allows for even cooking throughout chicken and other meats with uneven thickness. Simply place a steak, roast or other cut of meat on a cutting board and gently press on the meat using the tenderizer, making sure to avoid bones. Repeat this process again on the reverse side of the meat for greater results. Tiny heat channels are created, resulting in faster penetration of marinades, providing more even cooking throughout the meat, without changing the shape or appearance of the meat. The high-quality stainless steel blades will never dull, discolor, rust or change shape over time.
