I know, it seems like a ridiculous question in New England but I honestly haven't been able to find them! Little necks are trendy and everywhere but I'm looking for the big, meaty cherrystone or "chowder" quahogs. In the past, I've made chowder with the small "mahogany" quahogs which are always available at Whole Foods and have a great flavor but I'd love to find a source of the big ones. I've checked Mercato del Mare in the North End a few times but they haven't had them. I know you can order just about anything through them, but a place that carries them regularly would be awfully convenient. Also, T-accessibility is kind of a must because I don't have a car. Any suggestions?
