|this is a swede.|
2 leeks (white part only)
1/4 pumpkin (preferably not butternut)
3 small white sweet potatoes
3-4 small potatoes (or 1-2 large potatoes)
1litre stock (I just used a tetra pak of stock but you can make your own or just use water.)
Heat olive oil in pot (I use my le creuset). Add sliced leek and cook slowly until soft. Add other vegetables and cover with stock. Simmer until vegetables are soft. You may need to add more water. When vegetables are soft, puree.
