Hebrew National makes natural casing franks?
A lot of markets carry the Boar’s Head natural casing dogs. I usually get them at the Reading Terminal.
I had thought that Nathan’s natural casing dogs were not available in this area. I look whenever I’m in a market, but I’ve only seen the skinless ones. But while placing an on-line order from Acme the other night, I noticed they had them, so I ordered a pack. So if you live near an Acme, they may be there. Otherwise, the Boar’s Heads are your best bet.
