Easy test to determine whether you have real olive oil or a substitute.
Put it in the refrigerator.
Real olive oil will congeal. Not to Crisco but thicken.
Soy, peanut, etc won't.
(saw that on TV recently)
I don't know about that w/ Soybean oil. I keep a deep fryer outside and once it gets colder it congeals. Pure soybean oil. Again, not like shortening, but it does.
It could be b/c I've deep fried in it. IDK.
