re: What’s a normal or reasonable price for ox tails?

There was a Caribbean restaurant near my old office that we frequented. I got to know the owner a bit and told her I was going to make oxtail stew. She gave me some pointers and one was to be sure and include some coconut milk. I had made it before without that ingredient and it was good, but I thought it was much better with the coconut milk. She was from Trinidad, which has some Indian influence in their cuisine.

Note too that oxtails have a lot of fat. I like to cook it ahead of time, let it cool overnight, then skim off the excess fat.
