Dublin Bay prawns with mayonnaise is a traditional dish that's often found in seafood restaurants, especially along southern and southeastern coasts. It's usually made with a combination of fresh Dublin Bay prawns, lemon juice, mayonnaise, salt, and chives.

The prawns are placed in a pot of boiling water, drained, refreshed with cold water, and the meat is pulled out of the shells in one piece. The meat is left to cool down to room temperature, deveined, and the prawns are rinsed and dried with paper towels.

They're mixed with lemon juice, mayonnaise, chives, and salt, and the mixture is tossed so that the prawns are fully coated with mayonnaise. This dish (or a salad) is typically served on toasted bread or on a bed of shredded lettuce.
