Lava\u2019s ECO Grill Press is the perfect way to speed up the cooking process when grilling meats and vegetables. The premium enameled cast iron press surface fits into most round and square grill pans and is oven and outdoor grill compatible. Lava\u2019s Grill Press is designed to be preheated on the cook top or in the oven and then placed on top of meats, burgers and vegetables while cooking to weigh them down in the grill pan, skillet or on the griddle. This process creates more thorough contact with the cooking surface and the food which delivers more effective heating. Heating meats and vegetables from both top and bottom while pressing them down onto the pan\u2019s cooking surface can deliver as much as 25% to 30% faster cooking times. It\u2019s perfect for stove top grilling, griddling or pan frying. ECO premium cast iron offers a super-tough black matte enamel finish that is easy to clean and is incredibly durable. ECO grilling products offer a non-reactive cooking surface that doesn\u2019t absorb or transfer flavors or other chemicals to your food like pre-seasoned cast iron or other non-stick surfaces can do.
