On this episode of The Catch, we kick things off with a British staple: fish and chips and a visit with chef Nick Martino, owner of Aboveground at DC's Union Market. Then we hear how this iconic dish led to an interstate dispute between Iceland and the U.K. known as the Cod Wars. Host Ruxandra Guidi is joined by historian and Icelandic President Gudni Th.
