Celeriac rémoulade with Parma ham

Serves 6

This salad can be served as a starter, or as a light lunch accompanied by some crusty, peasant-style bread (Lisa Barber)

Celeriac is nutty and sweet, and the depth and richness of this dressing beautifully balances the smokiness of the ham. A scattering of walnuts strewn over at the last minute completes the dish. Serve as a starter, or as a light lunch accompanied by some crusty, peasant-style bread.

For the dressing

1 tbsp Dijon mustard
4 tbsp crème fraîche
Sea salt and freshly ground black pepper
1 celeriac
24 very fine slices of prosciutto
A handful of walnuts, roughly chopped
A few sprigs of parsley

Put the mustard in a bowl and stir in the crème fraîche. Add a small pinch of salt and a couple of grindings of black pepper. Set aside while you prepare the rest of the salad.

Using a sharp knife, cut away the outer layer of the celeriac, cut the remainder into eighth-inch rounds and then into fine batons. Spoon over the dressing and toss together lightly but thoroughly – your fingers are the best tools. Place a little dressed celeriac on to each plate, followed by a slice of prosciutto, and continue to layer. Scatter over the walnuts, a little very finely chopped parsley and serve.
