Where to buy smoked eel?
I'm pretty sure Russ & Daughters on Houston would have smoked eel.
For some truly sublime eel, call Ray Turner at Delaware Delicacies up in Hancock. He'll ship you some of the eel he catches, brines with honey and smokes over applewood in his backwoods smoking outfit. He's a real character - if you ever find yourself on the down-rent side of the Catskills (Delaware County), it is worth a trip to check out the stone smokehouse he built by hand.
His number is 607-637-4443.
