Ed, heavy cream you whip yourself is easily stabilized for up to a 3-4 day hold
in the fridge by using powdered sugar instead of regular sugar, or if you would
rather not use much sugar, throw in some meringue powder. Reddi-Whip and
home whipped cream collapse pretty quickly with use of regular sugar. I generally
use about 1/4 C. Powdered sugar for 8 oz. heavy whipping cream.
