Instructions
Mix the Greek yogurt, lemon juice, lemon zest, horseradish, dill, garlic, Dijon mustard, smoked paprika, salt and pepper in a small bowl. Cover and chill while you cook the shrimp.
Bring a large pot of water to a boil with the bay leaf and a generous pinch of salt. Fill a large bowl with ice water and set it nearby.
Add the shrimp to the boiling water and cook for 2–3 minutes, just until they turn pink and curl into a loose C shape.
Lift the shrimp out with a slotted spoon and drop them straight into the ice water. Leave them for 2 minutes, then drain well and pat dry.
Chill the shrimp in the fridge for at least 15 minutes, or up to 4 hours.
Arrange the chilled shrimp around the bowl of Greek yogurt sauce on a platter with lemon wedges and extra dill, and serve cold.
Notes
Poach 2–3 minutes only, then ice bath. A loose C shape means done. Sauce can be made a day ahead. Keeps 2 days refrigerated.
