Virgie likes to test OFTEN because she gets to sneak a taste of sweetness. This woman is a fiend for sugar. Sugar is to diabetics as crack is to crackheads. Oh, Grandma.
For those of you working by hand, get your friends and neighbors. You'll need them and their muscles. First, stir in a teaspoon of vanilla extract. Once that is incorporated, gradually (or have someone gradually) pour the hot syrup into the egg mixture while you or your stand mixer whips and whips and whips. After the whipper's arms get tired, have someone else take over. It helps if someone else holds the bowl during this aggressive, whipping action. Don't scrape the pan - the sugar left in the pan is at a different temperature. Just let as much drip out as possible.
When it's at the right consistency. WORK QUICKLY. The divinity dollops will harden very fast.
After they are cool and dry, you can store them in an air tight container. They make great gifts and look fancy on a platter of sweets.
