Where do you find this? How is it different from other shortenings?
There are a few places to order, intotheoven.com, countrykitchensa.com. and a few others. Some sell in small containers or the 50#.
Sorry, I forgot the answer you second question. It is a shortening made just for frostings. It is a smoother texture and for some people they say it doesn't leave that greasy feeling in their mouths. You use a little less of it than you would regular shortening. It is higher priced then shortening from the stores, but worth it.
I had wondered about this myself. I was in a grocery store last weekend and saw a 25LB tub of shortening and It was on sale and so I was looking frantically for the 'ratio status' haha. I never did find it tho. It didnt say a thing about 'ratio'. I guess this is why. Too bad. I'd like to find this 'high ratio' shortening in a local store 'convienently'. However I can still find good ol' Crisco before they made the changes but it's only at one store that I can find it nowadays.
Here is a thread were you can find lots of info on hi-ratio shortening. Info on where to buy, whats kinds of hi-ratio and much more.
