Great for defrosting!

We use this primarily for defrosting meats and it really works! Also great for heating delicate items like milk or chocolate :). Plus it is a good looking addition to the kitchen.More > < Less

Great simmer plate!

This is my SECOND purchase. I loved the first diffuser so much that I had to get a second. I have a gas cook top, and even "low" is often too high. This diffuser works perfectly, helps me to prevent burned cooking, and it's really the best diffuser I've used over the years. The hefty weight of this gives it staying power, unlike so many others. This is really a great product. Don't be fooled by similar plates on Amazon. Bella Copper diffusers are thick, heavy and have nicely milled edges. I'll never cook again without this product!More > < Less

About BellaCopper

Cooking Assist

Copper cookware is prized by kitchen connoisseurs for its unsurpassed ability to distribute heat quickly and evenly. But it’s an expensive metal, and copper pots and pans are an investment that many of us can’t quite justify. Thanks to Pete Mohler, there’s an affordable way to tap the conductive properties of copper without buying expensive new cookware.

Pete, who’s an aerospace engineer, came up with the idea for a copper heat diffuser when he wanted to improve the performance of a mediocre stove. He designed a solid copper plate that fits on top of a stove’s burner, under any ordinary aluminum, iron or stainless steel pan. The copper plate distributes heat evenly across the entire cooking surface of the pan, so foods cook more evenly and with less scorching and scalding. Pete teamed with Bill Hackman, and the two launched BellaCopper to commercialize the idea.

BellaCopper’s hand-finished heat diffusers come in different sizes for maximum versatility. You can use two diffusers side by side to turn two adjacent burners into a single griddle-sized heat source, for example. You can use them as hot plates to keep food warm, or in the oven to maintain a more constant baking temperature. BellaCopper’s heat diffusers also double as defroster plates: If you place two frozen chicken breasts on a room-temperature copper plate, they’ll defrost in about 40 minutes as the internal heat from the plate is transferred to the frozen food.

Who knew a simple copper plate could be so useful in the kitchen?
