Hi,

There is a product called "insta-gel" that can be purchased at bakery supply outlets. One teaspoon for every two cups of whipping cream does a good job of stabilizing whipped cream.

Also here is a recipe for making whipped cream hold up!

Ingredients:

1 tsp unflavored gelatin
4 tsp cold water
1 c heavy whipping cream, chilled
1/4 c 10x sugar

Method:

Sprinkle gelatin over water in small pan, allow to sit 3 minutes.
Place pan over low heat; stir constantly until gelatin dissoves about 3 min. Remove from heat and cool slightly.
Whip cream until slightly thickened. Slowly beat in the sugar; then slowly beat in gelatin mixture. Whip at high speed until stiff.

Hope this helps some!
