Sweet Potato and Leek Soup (with bacon)

Adapted from Picnics by David Herbert

4 slices bacon, chopped
1 leek, chopped
1 onion, chopped
1 carror, chopped
1 clove garlic, chopped
1 1/4 lb sweet potato, peeled and cut into chunks
2 pints vegetable stock
Salt and pepper to taste
Sour cream

Cook bacon over medium high heat for 2-3 minutes. Add the leeks, onion, carrot, garlic and sweet potato. Cook, stirring, for 5 minutes or until the leek and onion have softened.

Add the vegetable stock and bring to a boil. Cover and simmer for 25/30 minutes, until the vegetables are tender. Purée the soup in a blender in batches.

Serve with a dollop of sour cream.

Makes a big pot of soup. I will be freezing for a future meal.
