I am responding to a request from a comment by chrisrich on one of my photos. Sorry ...didn't have your email to pm the response to so here goes.
I believe I got this recipe from this site. It's great tasting and works like a charm.
2 lbs. or 1 kg. bag of confectioners sugar
1 pkg dream whip ( I used an 85 gm. pkg...sorry Canadian pkgs. marked in metric, but the package was 1 envelop from a 2 envelop box)
2 cups crisco shortening
1/2 cup boiling water
1/2 tsp. salt
2 tsp. clear vanilla
1 tbsp. clear corn syrup
whip until fluffy. No need for refrigeration, but will keep in the fridge as well. Great taste and crusts well.
Good luck & happy baking 
I would use high ratio shortening for this recipe. It makes the recipe above a lighter tasting icing.
I tried it with crisco first and it was o.k. then I tried it with the high ratio shortening and it was fantastic,
lilscakes,
May I ask where you got 'clear corn syrup' in Canada??????????
I've searched every grocery store I know, but they only sell the golden corn syrup.
Thanks,
Purple Petunia
