Classic Prawn Cocktail

Step 1

Pour the mayonnaise into a small bowl, then add the ketchup and fresh lemon juice to the same bowl.

Step 2

Stir the sauce with a small spoon, mixing until the color is a light coral pink and the texture is smooth throughout, about 30 seconds.

Step 3

Taste the sauce and sprinkle in a small pinch of salt and pepper, then stir to combine.

Step 4

Place one romaine lettuce leaf into the bottom of each of two cocktail glasses, pressing it gently so it cups the inside of the glass.

Step 5

Pour half the sauce into each glass, spreading it evenly over the lettuce with the back of a spoon to coat the bottom.

Step 6

Divide the cooked prawns evenly between the two glasses, arranging them in a single layer on top of the sauce.

Step 7

Drizzle the remaining sauce over the prawns in each glass, then cover the glasses with plastic wrap and refrigerate for at least 5 minutes before serving.
