This elegant shrimp salad on buttery toast is a Swedish classic, perfect for springtime entertaining or a light lunch. Aquavit chef Emma Bengtsson uses tiny pre-cooked shrimp from Sweden (available at IKEA or online): their delicate briny flavor is important to the dish, and an ingredient worth seeking out.
Shrimp: In a bowl, add shrimp, mayonnaise, juice from half a lemon, and salt to taste. Pull the dill fronds from the stems and roughly chop to get 2 tablespoons, loosely packed (reserve the rest for garnish). Add to the shrimp mixture and stir to combine. Set aside.
Toast: Slice the bread into ¾-inch slices. Heat a large skillet over medium heat and add 1 tablespoon butter. When melted, add enough bread slices to fill the pan (about 3). Reduce heat to low and cook 30 seconds. Divide and spread 1 tablespoon butter evenly over the top sides; then flip and cook bread another 30 seconds, adding more butter to the pan as needed. When toast is golden on both sides, transfer to several layers of paper towels to cool, 30 seconds. Cut crust off of toast and slice each piece horizontally into 2 triangles.
Assembly: Place toast on a platter. Arrange a lettuce leaf on top of each triangle, making sure the leaf is about the same size as the toast, then add the shrimp. From reserved lemon half, cut three thin slices (wheels), and cut each wheel in half. Make a cut in the middle up to the peel, then twist and place over the shrimp. Garnish with small dill sprigs before serving.
