I do use vegetable shortening in my icing, along with butter. I saw that the FDA is wanting to eliminate trans fat and partially hydrogenated oils from the food of Americans. I switched to a generic brand when Crisco changed their formula.
I guess this will mean changes for people who are using high ratio shortening too.
I really don't want to go to all butter. Guess I'll wait to see what the shortening brands come up with.
