Ingredients:
2 cups sugar
1/2 cup cara cara orange juice
4 egg whites
1 tablespoon vanilla
pinch salt
zest of two cara cara oranges
food coloring, if desired

Directions:
In a medium saucepan, bring sugar, vanilla, zest and juice to a boil, stirring occasionally. Continue to boil until it reaches soft ball stage (when a drop of the syrup forms a soft ball when dropped in cool water) while continuing to stir occasionally. Meanwhile, beat the egg whites and salt to soft peaks. Keep the mixer running (you need a stand mixer or a friend to complete this next step) while you strain a continuous stream of the molten syrup into the egg whites. Add the food dye. Beat for about 5 minutes or until the frosting is fluffy, glossy and cool. Frost cooled cake/cupcakes.

My thoughts:

An creamsicle meets marshmallow fluff frosting.
