This is a wonderful alternative to potato salad.  Peel the celeriac with a small sharp knife, not with a vegetable peeler – it takes too long!

Serves 4-8

1 medium celeriac
6-8 tablespoons Mary Berry’s Mustard Dressing
juice of 1 lemon

Using a large sharp knife, cut the celeriac into quarters.

Carefully peel the skin off thickly using a small sharp knife.  Coarsely grate the celeriac either by hand or in a processor.

Blanch in boiling salted water for about 1 minute, drain in a colander and refresh under cold water to stop the cooking.  Drain well.

Tip the blanched celeriac into a salad bowl and toss together with the Mary Berry’s Mustard Dressing, lemon juice and season with salt and pepper.  Serve chilled.
