LOL janathema, dried beans are still called bean
Read some of these, the last on the list is the first to try. Use a large whisk, and if you can find to buy, use a prctice golf ball in the whisk. Chef challenged us n class, two teams, one on an electric mixer, the other by hand. I was the one by hand an lost miserably. So, I learned to do this by hand.http://www.freerecipe.org/Dessert/Ba...s/Sponge_Cake/
The last recipie, if you cook it longer at lower temp, the final cake is dry and hard. There are probably tweeks that the mass producers do to get the 'store' product to be the way it is, but if you were doing this at home, this is where you would start.
Oh, here is a pic of the golf balls, just so you know what i mean. They really work and sell for about $5 canadien for a dozen. They really get the air incorporated into egg whites. Don't work for whipping cream though. Tends to collapse it :(
