Parnsip and Celeriac Soup with Cream and White Wine

Yes. We're *still* using up the Christmas leftovers...

For 4-6 portions you need:
1 onion, chopped
1 leek, sliced
3 parsnips, peeled and diced
1 celeriac, peeled and diced
50g butter
2 tbsp ground nut oil
1-1.5 litres light vegetable stock
125ml double cream
250ml white wine
salt and pepper

Sautee the vegetables in the butter and oil, covered, for about 15 mins till tender. Add the wine and allow to boil for a minute or so. Add the stock and season. Bring to the boil and simmer covered for about 15 mins. Blend to a smooth puree, adjusting the seasoning if necessary. Serve with a dash of cream and some fresh chives snipped over the top if you have any.
