I'm wondering if there is a correlation between the smoke point and the darkness of the patina -- the higher the smoke point the lighter the patina, or if the patina is unrelated to the oil entirely.
I just tried seasoning with refined canola oil and there was much less smoke and MUCH less stink, and the patina is pretty dark. Far better than Crisco Vegetable Oil, which I believe is refined soybean oil. This is strange because refined Soy oil is supposed to have a higher smoke point than refined Canola. Perhaps Crisco oil is not refined, or perhaps soy oil is not soybean oil.... :-?
I would like to switch to the extra light olive oil, and in general I always wanted to simply season with olive oil, but I'm not sure it can strictly be considered a "neutral" oil, that is, neutrally flavored. Some chefs with overactive palates may always detect it....
Thanks, Jeff, excellent link. 8-)
