This method ensures each shrimp is cooked exactly the same, making each delicious bite of this creamy, hearty pasta salad consistent and beloved. Since the recipe calls for cutting the shrimp in thirds, it’s important to pick up some larger, fresh shrimp from your favourite purveyor. Leaving the tails on adds more flavour, but it also helps to protect the tail while cooking, which ensures it’s a consistent, sweet bite like the rest of the shrimp.
