A Swedish speciality of shrimp on toast. From Jamie Oliver who says: "To all intents and purposes, this dish is the Swedish equivalent of our prawn cocktail. As much as I love that when it's done properly, the flavour combo of ketchup and mayo isn't the biggest turn-on in the world. This, on the other hand, uses generous amounts of lemon and dill in the mayonnaise and the result is clean, zingy and zippy in flavour – I'd expect nothing less from the Swedes. It involves hardly any work, but if you pile a spoonful of these dressed prawns on a toasted piece of brioche or sourdough bread you'll have a really confident little light lunch or starter."
