Old Dutch 10-Inch Beating Bowl, Copperby Old Dutch (767) | |||||||||||||||||||||||||||||||||||||||||
  | | customer review: Copper bowls with lacquer make them no different than regular plastic bowls.
| The coppper in real copper bowls helps create a tighter chemical bond in reactive sulfur items such as egg whites. The bond created is so tight that the sulfurs are prevented from reacting with any other material. This gives you the stiff peaks you're looking for. Cream of tartar does the same thing. Use a lacquered bowl and you might as well be using a cheap $5 plastic bowl. Old Dutch Copper Beating Bowls and Whisk, Set of 3by Old Dutch (964)  $48 customer review: These bowls are beautiful and the price is very reasonable. Couldn't find them cheaper anywhere else. They are a very nice addition to my copper collection. Shipping for the item was very fast.
| Loved them! Mauviel Copper 8-Inch Egg White Bowl with Ringby Mauviel (2191.20)  $65 customer review: There's two ways to work this bowl: Either set it into a heavy ceramic mixing bowl as a "nest" or carry it in the crook of your arm with your thumb through the ring. Either way is comfortable. When nested in a ceramic bowl, this Mauviel is stable enough to tilt it toward your whisking hand so that you have an easier wrist angle than if you used an ordinary flat bottom bowl.
| If you want to chill the ingredients, put cold water or water and ice in the ceramic nest bowl; if you want to warm the ingredients, use hot water in the ceramic nest bowl. 'Dem Frenchies ain't as dumb as we often like to think -- this works GREAT! 8-Inch is the smallest reasonable size for this type of bowl. Consider getting a larger one if you whip a significant quantity of egg whites. I think a larger bowl of the 10.6-inch Mauviel allows me larger movement of arm and whisk which makes more bubbles and gets the whites to stiffen up faster. The 12-inch seems like more than I need most of the time. You've got to judge it for yourself before buying. (We got into this stuff back when plain copper was dirt cheap.) Nothing matches copper in this work. Read up on the chemistry involved and understand that eggs whipped in this bowl can give you as much as 25% of your recommended daily allowance of copper. Avoid the Old Dutch copper bowls (we have the large and the medium). They are thin, dent at a touch and warp out of round just by holding it when whipping. The Mauviel feels so strong that I would wonder if I couldn't stand on it safely. The Old Dutch would crumple if our cat jumped on it. Everytime I look at it, mysterious new dimples appear. Mauviel Copper 10.6-Inch Egg White Bowl with Ringby Mauviel (2191.26)  customer review: I use this bowl for whipping up eggs whites but is can be used for mixing dry products also. It's very heavy and sturdy and I highly recommend it. | Mauviel Copper 12-Inch Egg White Bowl with Ringby Mauviel (2191.30) customer review: I have always found that egg whites beaten by an electric mixer were too foamy. Almost like soap bubbles. This copper bowl makes them creamy and appetizing. They are very stable and it simply makes fantastic merinque.
| Why reinvent the wheel? People have been doing this for hundreds of years. It really doesn't take as long as you think, nor is it as difficult as you may think. I was watching Sara's Secrets on the Food Network while Bill Yosses was the guest. I was very impressed with him so I borrowed his book Desserts for Dummies. In it, he says that a 12" diameter bowl is best while ~ 7qts is a good volume. He was correct. This bowl seemed huge, but when eight egg whites triple in volume, it fills it up by two-thirds. It is a fine size. The copper is beautiful. I hang it over my kitchen. I had no reservations about quality before I ordered and I was correct in my assumption. Mauviel makes quality products. I would consider this heirloom quality. The walls are very sturdy. The round bottom is essential to whipping egg whites. Beating (not whisking) the egg whites is so much more efficient and less tiring with the round bottom. While if it had a flat bottom, it would quickly ruin your whisk. Believe me I know. It does have a ring which makes it easier to grasp. I also put a towel underneath that I have bunched up in a circle. This adds stability on a slicker countertop. I highly recommend this product.
