This is best done with a stand alone mixer or 1 person holding a hand mixer and another person adding the ingredients... It can not be done by hand. You will also want another set of hands to help drop these candies before they stiffen. I don't know any way to soften this mixture once it has set.
These are wonderful to eat and a very pretty addition to any party. Any flavor of Jello will work.
In a medium saucepan over a low burner, combine sugar, Karo, vanilla and water. Bring to a boil, stirring to dissolve sugar. Heat to 250-265° or to a hard ball stage.
Meanwhile, beat egg whites until stiff; slowly add gelatin while beating until stiff peaks form. Continue beating and slowly pour syrup mixture in a thin stream over the egg mixture. Beat until mixture thickens and loses its gloss. Stir in nuts.
Work quickly and drop by teaspoons onto wax paper. These will stiffen quickly. After cooling, place in an airtight container.
