Scalloped Kohlrabi

ingredients
175 g (6 oz) onion, skinned and thinly sliced
3 Tbsp (40 g) butter
2 lb (900 g) kohlrabi
7 fl oz (200 ml) milk
salt and freshly ground pepper
chopped fresh parsley to garnish

method
1. Soften the onion in 25 g (1 oz) butter in a covered pan.
2. Thickly peel the kohlrabi to remove all the woody outer layer. Slice thinly and layer with the onions and seasoning in a 1.7 litre (3 pint) lightly buttered shallow ovenproof dish, topping with a neat layer of kohlrabi.
3. Pour over the milk and dot with remaining butter. Place on a baking tray and cook in the oven at 200°C (400f) mark 6 for about 1 1/2 hours, until tender.
4. Garnish with chopped parsley for serving.
