Stockholm's best-known herring cart stands by the water at Slussen, and locals queue at lunch for fillets served on crispbread or rolled in soft flatbread.
Butterflied Baltic herring fillets are breaded and pan-fried until crisp, then served on crispbread or in soft flatbread with mashed potato, pickled cucumber or red onion, and lingonberries. It's sold hot straight from harborside kiosks and food trucks around Stockholm's waterways.
