just make sure its FRYING oil, and not like crisco pan coating
Crisco and other solid fats are, in my opinion, far better for frying. The liquid shortenings have an additive to keep them from congealing, and I'm of the opinion that it's what makes the grease gum up around the inside of the fry well/on the baskets/on the elements, as well as making it easier to scorch the grease. We always used solid shortening when I was in the military, because it was easier to store and had more uses (it could also be used in breads and cake frostings).
Other than that, Euphonic is right on. That's pretty much how I've seen blooming onions done. I could ask my pal who lives up yonder about it (I probably should have already...derp), but the last time I was in Boston, I didn't see a lot of chain places known for the onion.
There's a fucking amazing Brazilian place in Everett, though, if you're ever in the mood for some of that.
Your Pal,
