This stunning bowl from French company de Buyer is as beautiful as it is functional, made of 100% solid copper. This style of half-round mixing bowl is the classic tool used by bakers to whip egg whites into stiff peaks to incorporate into desserts and beyond, as the shape adds extra air the the mixture and the copper keeps the peaks glossy and supple through its ability to promote a certain type of bond between the egg proteins. A side handle adds stability, while the open-rolled edge makes for easy cleaning.

Care and Use

Care: Clean lightly with water and soap and use white vinegar to remove oxidation. Do not dishwash or use abrasive scrubbers. Dry immediately and do not let soak, as will speed tarnishing.

The neat thing about whipping egg whites in a copper bowl is that as the whisk hits the bowl, tiny bits of copper break off from the surface of the bowl and mix in with your egg whites.

Since copper can bind sulfur groups, those tiny bits of copper bind to the egg white proteins and therefore, those sulfur groups are unable to form the strong disulfide bonds that can lead to gritty, dry whipped egg whites. Therefore, egg whites whipped in a copper bowl stay glossy and firm without as much risk of becoming overwhipped or grainy.

Not sure how you’d use it?

We test everything we sell. Here’s how we’d use this.

HOW TO USE

Use for whipping egg whites for meringues and airy angel food cakes. The bowl is also ideal for the top of a double boiler, simply nest the bowl over a pot with simmering water for temperature-controlled melting of chocolate, egg yolks and other slow-heated ingredients.

Kitchen Notes

The natural oxidation of the metal should be polished off the interior of the bowl when it appears with white vinegar. Never put the bowl in dishwasher and never use abrasive cleaners or abrasive sponges or steel wool as to not scratch the copper. One washed, dry immediately and do not let soak—water left for too long will cause tarnishing.
