Run the blade of a vegetable peeler along the celery sticks to create shavings. Transfer to a bowl of ice-cold water to curl.

Slice the pears thinly and arrange in a serving bowl or on a platter. Top with the celery curls, a scattering of chervil and half the prawns. Drizzle with the garlic mayonnaise and serve.

To make the mayonnaise: Add the egg, lemon juice, mustard, garlic and salt, to taste, to a blender and blend until combined.

With the motor still running, slowly add the oil in a thin, steady stream until the mixture takes on a thick, creamy consistency. Fold in the crushed walnut.
