Sweetcorn and Prawn Salad

Method

1. 1 Boil the sweet corn for 8 minutes, then separate the kernels while they are still warm to keep them separate and sweet.
2. 2 Boil the shrimp for exactly 2 minutes, then soak them in ice water to firm up the meat.
3. 3 Soak sliced onions in lemon juice for 10 minutes to reduce their pungency.
4. 4 Mix mayonnaise with lemon juice, pepper, and chopped dill to make a sauce.
5. 5 Mix the corn and shrimp with the sauce, let it chill for 15 minutes, and serve on a lettuce leaf.
