It is a crisp salad, very similar to a Coleslaw. It will last for 1-2 weeks in the fridge.
1 head of celery, washed and stalks thinly sliced
1/2 large red onion, peeled and sliced (optional)
1 cup Mayonnaise or a 50/50 mix of Crème fraîche and sour cream
1/2 tsp. dry mustard (Coleman type)
1 tsp. rock salt
Freshly ground black pepper to taste
Mix celery and onion in a bowl.
Place all dressing ingredients in a jar and shake well.
Pour the dressing over the celery/onion mix, stir well and transfer to a serving dish.
Cover with a cling film and chill in a fridge. If you want to store it for a few days, keep in an airtight container.
You can also add any of these things; 1 crisp apple, 1 grated carrot, a couple of sliced green chillies, a few raisins, walnuts, fine lemon rind.
If you do not eat mayonnaise, use a vinaigrette of choice.
