Need a blender for this. Filling and warming, it's a bit like lentil soup.
Ingredients:
1 medium sweet potato
1 onion
about 25g or one dessertspoon margarine
3 carrots
1 teaspoon curry powder, or cumin or coriander
2 dessertspoons creme fraiche or natural yogurt
1 - 1 and a half pints (500 - 750 ml) stock
salt and pepper to taste
Chop the onion and fry in the margarine in a large pan for a few minutes, adding spices. Peel and chop the sweet potato into chunks and add to the pan. Add the peeled and sliced carrots and fry gently until the onions are fairly soft. Add the stock, bring to the boil and simmer until all vegetables are tender. Blend in blender until smooth, then mix in the creme fraiche. Check seasoning and add salt and papper if needed (but it probably won't be). Thin out soup with a little water if required - it should be fairly thick.
