A rubber gaskets primary purpose is to create a constant tight seal

A rubber gasket’s primary purpose is to create a constant tight seal. Over time a gasket can dry out and lose its elasticity. If you notice this happening, replace the gasket immediately. A worn out gasket can lead to steam not building up, or worse, escaping from your cooker.

This 11 by 19 1 2 inch heavy cast aluminum griddle fits over two gas or electric rangetop

This 11-by-19-1/2-inch heavy cast-aluminum griddle fits over two gas or electric rangetop burners, including flat surface rangetops, making it easy to cook for a large group. Use it to grill sandwiches and meats, or to cook your world-famous, all-you-can-eat breakfast of eggs, bacon, sausage, potatoes, veggies, French toast, and pancakes. The easy-to-clean nonstick surface is reinforced with stainless steel, which forms a permanent base for the nonstick coating. That means it will last up to 100 times longer than other nonsticks–thus its name, the “Ultimate Griddle.” The recessed channel drains away excess fats from your bacon or sausage. The commercial-grade cast aluminum conducts heat more evenly than other surfaces, and at lower temperatures–in fact, you should use only low-to-medium heat with this griddle. As an added feature, the superconductive aluminum also works well to thaw frozen foods without the use of heat (steaks in 30-45 minutes, chicken in 20-30). Use only wooden, nylon, or nonmetallic utensils. Hand wash without abrasives. –Doree Armstrong
