I used to only use it in baking. Then when I started making fondant cakes, I found out that rubbing crisco all over my hand, keeps fondant off.
Also fried chicken in it, crispy yum.
Then found it very useful when kneading dough. The same way as fondant, it kept the dough off my hand. Perfect!
I suppose other brand works the same way. I just haven't had the chance to try other brand.
