I have been using hi ratio shortening for my icing for some time now and am getting ready to order some more and saw that some is labeled 'for icing' and some labeled 'for icing & baking''. So, what's the difference? I can't seem to find the info. I'm looking at the Sweetex brand. I do make a high ratio chocolate cake pretty regularly and would be interested, but really can't tell the difference. Any info would be greatly appreciated.
