Love escargot! Butter, garlic, mmmmmm!
Also like conch. Can't remember if I've ever tried abalone.
As for calamari, Chef Mario Batali says you cook it either for two minutes or two hours. Quickly done, it is tender and not at all rubbery. Let it go more than a minute or two and you do have to cook it a long time to get it tender again.
We were out to dinner with friends last Friday at the CIA in Hyde Park, NY. Went to their Italian place. I had a rabbit ragout that was outstanding, and for the main course, oxtail. Soooo good! Tender and delicious. The couple we were with couldn't imagine why I wanted to eat oxtails. Until they tried it.
We have chicken feet in the freezer, as well as pig's ear. Don't know if we'll like it, but hey, you never know until you try, right? We've always told our kids to just try anything once. If they didn't like it, that was fine. But they had to at least try it. Those three will eat just about anything now.
