If you are adding pecans or cherries prepare them ahead of time. The cherries need to be drained and then put on top of paper towels to get them as dry as possible.
Measure the sugar, corn syrup, and water directly into a medium saucepan and stir thoroughly to combine ingredients.
Place the saucepan on medium heat and do not stir again.
As the sugar mixture heats, it will begin to bubble. It takes about 10 minutes or so for it to reach 265 degrees.
While the sugar mixture is bubbling, prepare your egg whites in a heat proof bowl. Separate the egg whites from the yolks. Beat egg whites until stiff peaks form.
Chop pecans or cherries if using.
Prepare a place to put your finished divinity. My favorite and easier way, was to line an 8X8 pan with parchment paper and give it a light spray of non-stick spray. .
When the sugar mixture reaches 265, turn off heat and remove the pan.
Holding the hot sugar mixture pan in one hand and your mixer in your other, carefully pour the hot sugar into the egg whites as you beat the egg whites and sugar on low speed.
Once all the sugar is mixed into the egg whites, continue beating the divinity for about five minutes. The mixture will thicken and lose its gloss.
Stir in the chopped pecans.
Pour onto your prepared surface and let set up for a few hours.
Remove from pan by lifting carefully the sides of the parchment paper. Cut into small squares.
Store in an airtight container.
