Celeriac Remoulade

(serves lots of people at a picnic)

1  head celeriac (celery root), peeled

dressing: olive oil, mayonnaise, wholegrain mustard, lemon juice (in proportions to suit your taste)

Here is where any obsessive-compulsive tendencies will come in handy.  Julienne the celeriac by cutting VERY thin slices and then cutting those slices into VERY thin slices.  Toss with the dressing and serve straightaway.
