Leek and Potato Soup

This a soup that I made to use up excess vegetables from the box.

Ingredients
2 tablespoons Butter or margarine
1 clove grated Garlic
two good sized Leeks( about 500g)
Potatoes (about 500g)
900 mls hot water with two chicken stock cubes
Salt to taste
1/4 teaspoon black Pepper
1/2 pint Milk or cream

1. First, clean and chop the leeks. Melt the butter / margarine in a pan and add the chopped leeks and garlic. Fry them over a low to medium heat until the leeks are soft. This will take about ten minutes. Stir frequently so that none of the ingredients brown.
2. Peel the potatoes and chop them into cubes. Add all the remaining ingredients to the pan with the exception of the milk / cream.
3. Bring the soup to the boil and then let it simmer (just barely boiling) for the remaining cooking time.
4. If you want the potato to stay chunky, cook for 15 to 17 minutes until the potato is soft. If you want to blend the soup, cook for about 20 minutes.
5. Blend the soup till smooth if thats the way you like it.
Just before serving, pour the milk / cream into the soup and stir well. If you plan to freeze some of the soup, don't add the milk / cream to the pan, instead add three tablespoons of milk / cream to each soup bowl.
