This professional-grade tool, with stainless-steel prongs to break down tough meat fibers, provides controlled, uniform meat tenderizing before they're marinated so flavors penetrate deeply. It will also improve the texture of poultry, fish or beef while also reducing the marinating and cooking times. Small holes created by its 24 spokes allow for better absorption of marinates and even cooking. A practical solution for turning a tough piece of meat into a delicious, tender one. The 2-inch-diameter plastic disk on the bottom is spring-loaded. It provides precise control when the tenderizer's handle is pushed down, so the prongs pass through the disk's holes and into the meat. When you release downward pressure, the handle springs up again, poised to tenderize another section with the same smooth, uniform action. This durable, heavy-duty tool (7-1/2 inches high) will last a lifetime. It's dishwasher-safe, too.
