Swedish Creme - Dessert Fav

This dessert is one of the best and easiest ones I've ever made.  It's from Gwyn's High Alpine Cookbook/Snowmass, Co. 

In a double boiler combine 1 cup sugar, 2 cups heavy cream, and 2 tsp. gelatin (unflavored).  Cook for at least 10 min. until the sugar has dissolved.  Cool.  Add and beat in 2 cups sour cream and 2 tsp. vanilla.  Pour into wine glasses or small dessert dish, 2/3 full.  Top with fresh sliced fruit (strawberries, kiwi, raspberries, blackberries, blueberries,  etc)  1 1/2 recipes serves 10.  I use antique jelly jars (garage sale find)
