This is a recipe that one of the senior missionary sisters gave me in Hawaii. It was a hit at every luau she brought it to. Be aware that it does serve a lot, so it is not something you would fix for a small family, unless you want to eat it for the next few days. It does hold up for several days, if you are sure to thaw the berries before you put it in the whipped cream.
1 can sweeten condensed milk
1 12 oz tub of a dairy whip (or larger if you want)
1 package of thawed triple berries (Costco, Sams)
Allow the berries to thaw for about an hour before you start this.
First mix the condensed milk and the dairy whip together in very large bowl
Then add the thawed berries and carefully blend into the creamy mix
Refrigerate until time to serve. Serves many.
