A quintessential and must-try traditional snack for adventurous visitors in Iceland is hákur, which consists of cured Greenlandic shark that has undergone a rigorous fermentation and drying process to neutralize its natural toxins. Additionally, visitors frequently sample hardfiskur—air-dried white fish flakes typically slathered generously with fresh butter—which serves as a protein-rich, savory snack beloved by locals. For those preferring modern comfort foods, grabbing a traditional Icelandic hot dog loaded with crispy fried onions, raw onions, sweet brown mustard, and remoulade from an iconic Reykjavik stand is an essential culinary ritual.
