Copper Diffusers

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?

    Hello nice Daily Grommet people. I developed the BellaCopper solid copper heat diffuser and defroster plates to solve a cooking problem I was having – and it worked so well that I decided that I had to share it with everyone. I think everyone who cooks needs at least one. They really work great- it's the copper. I'm here to answer your questions.

    Do they work with electric stoves also? You show only gas ranges.

    @ Kate

    Hi Kate, well they are flat so liquids will run off and make a mess- it is best to cook in a pan on the BellaCopper heat diffuser. That being said, I have toasted tortillas on them - works great for that

    What would be the best size to buy for the most versatility?

    @ Alice

    Hi Alice, on my stove I use the 8 and 9 inch ones most often. The 10 inch one is really quite large. What is important is not the size of your burner grate, but the contact area on the bottoms of your pans.

    However, for defrosting I use the 10 inch one - more area and more thermal mass.

    Great idea! Curious, how thick are these?

    @ lauren

    Hi Lauren, they are all 1/8 inch thick. that is really quite substantial - the 10 inch one weighs 4 lbs!

    I have a Viking gas stove and just purchased a terra cotta tagine. The manufacturer of the tangine recommends using a heat diffuser for a gas stove - do you think yours would work for this product?

    @ Ann

    Hi Ann, we have many customers that use our copper heat diffusers with their tagines. It works great for this because it minimizes hot spots.

    Are these primarily/only for gas burners?

    Would they be suitable for electric burners?

    Thank you

    Do these defusers hold their shape over long use? Or do the buckle over time?

    @ Carole

    Hi Carole - no, we never have had a warping problem. We have been making these for over ten years, and have had the same ones on our home stoves for over eleven years. Copper has a higher melting point than aluminum, and our heat diffusers are thicker than all commercial copper pans

    Do they need any special cleaning? Will they discolor with every handprint?

    @ Anna

    Hi Anna, yes finger prints will discolor them - and in fact, they will change color from the very first use.

    Some people clean them, some don't, and some only clean the tops.

    I bought the 8 inch plate and love it. Defrost foods evenly and timely. I also just bought a new range and still getting used to the various burner levels. Works great for smaller pots, but haven't tried multiple pots on one. Great product!

    Do I need to use a different size plate for different sized burners? How about different sized pots? If I purchased a 10" for each of my burners could I use any size pot on them?

    @ GrammieOfSeven

    Hi GammieOfSeven - you can always use a smaller pan on a larger Copper heat diffuser, in fact you can use 2 smaller pans on one larger heat diffuser, set diagonally, if you want. what is important is that the copper plate is larger than the surface contact area of your pans. That being said - the ten inch ones are really quite large and I use the 8 and 9 inch ones most often on my home stove.

    I want to get a 2 burner cast iron griddle, would I need two 10 inch plates? Also I have a glass top stove. thank you.

    @ Debra Kelly: The BellaCopper heat diffusers work on gas, electric, and glass/ceramic top stoves. You want to make sure the plate have full contact with the bottom of your griddle. So depending on the size of your griddle, you might need two 10" plates or a 10" with a smaller size plate. We also offer the 6", 8 " and 9" square plates.

    Hello,

    Would this be useful for simmering for long periods of time - something like spaghetti sauce - to keep from burning? I used to have an asbestos pad, but they are not safe to use...thanks

    How do you clean the tops when things splash on them etc.
