The Pylsur Pilgrimage

The Icelandic hot dog is not what you expect. The sausage is made from a blend of Icelandic lamb (free-range, grass-fed, no antibiotics - Iceland takes this seriously), pork and beef, giving it a slightly gamey, distinctly non-industrial flavour. It's boiled or steamed, nestled in a warm, soft bun, and loaded with "the works" ("eina med ollu"): raw white onion, crispy deep-fried onion, ketchup, a sweet brown mustard (pylsusinnep) and remoulade (a mayo-based sauce with sweet relish). It costs about 500 ISK - roughly three pounds - and the combination of sweet, sharp, crunchy and savoury is absurdly, unexpectedly perfect. Baejarins Beztu Pylsur, a tiny stand by Reykjavik's harbour, has been serving them since 1937 and regularly appears on "best street food in the world" lists.

The furthest pin on the map, and the most unlikely pilgrimage in the collection. Reykjavik is a city of 130,000 people on a volcanic island in the North Atlantic, with colourful corrugated-iron houses, geothermal swimming pools you can soak in outdoors in winter, and a landscape that looks like another planet ten minutes outside town. Flying in to eat a hot dog sounds absurd, and that's exactly the energy. The most northerly, most surprising, and arguably most fun pilgrimage on the entire site.
