Good idea. I wouldn't trust it. Was it a store brand? I am asking because I was short on my high ratio, and Stop n Shop had Guaranteed Value Brand with trans fats in it. I looked at the date, and it was expired. I stuck with Crisco. I brought it to the attention of the store manager, and apparently they didn't care, because the same cans are there with the exp. date of 08/10! Can you imagine?
I use hi-ratio all the time and I've never seen it yellow or have an odor to it at all. It simply smells clean, maybe a little like vegetable oil if I had to describe it. Sounds to me like you got some really OLD shortening.
