The salt & vinegar potato martini

James Bond has cast aside his vodka martini in favour of a Euro pale lager in the newest 007 flick, but that's not about to stop mixologists creating ever-weirder martinis.

Eoin Kenny, from London's L’Atelier De Joel Robuchon, has come up with an earthy 'potato' martini in the classic crisps flavour salt and vinegar by combining potato vodka, quince vinegar, liqueurs and elderflower cordial.
