Elizabeth David's Chicken Salad

Make the fresh mayonnaise - it really is worth making it fresh for this recipe. If used grate a couple of tablespoonfuls of fresh horseradish and stir into the mayonnnaise. Scrape and boil the potatoes, clean and slice the mushrooms, and cut the chicken into small pieces probably excluding the leg and thigh  Picture  .

Hard boil the two eggs. Quickly cook the prawns in a very little olive oil until pink, take out and allow to cool on some kitchen paper. When cool take of heads and shells, and season with a little salt and lemon juice. Discard the outer leaves from the lettuce and separate out the heart leaves.

Dilute the mayonnaise with a few spoons of warm water until runny. Season the potatoes, mushrooms and chicken pieces with salt, put in a serving bowl and stir in about three quarters of the mayonnaise then cover with the remaining mayonnaise.

Place the lettuce leaves and prawns on top of the potato/chicken/mushroom mixture, and then grate over the yolks from the hard boiled eggs. Serve  Zoom  .
