Potato & Celery Soup

Potato & Celery Soup
I have found this soup recipe which my Grandma used to make, its quite basic and very easy to make, also very tasty!

2oz Butter
1lb Potatoes, peeled & chopped
2 Onions, peeled & quartered
5 stalks Celery, washed & chopped
1 1/2 pints Chicken or Vegetable stock
1/4 pint Milk
Salt & Pepper
Nutmeg

Melt the butter and fry the vegetables gently for 5 minutes. Add the stock and salt & pepper, bring to the boil, cover and simmer for 20 -30 mins or until the vegetables are tender. Sieve or liquidize the soup. Add the milk and reheat. Season to taste and grate in a little nutmeg. To serve, garnish with a few chopped celery leaves.
