2 leeks, 3 carrots and half a swede, all chopped. Melt 1oz butter in a large pan, add veg, stir till coated and cook for a few minutes till softening. Sprinkle over 1oz flour and mix in. Add 1 pint chicken or vegetable stock, stir well and simmer till veg is really soft. Blend to a puree. Add a quarter pint of milk and a splosh of double cream.
Chop up an onion, 3 carrots, 2 parsnips, 2 leeks, a Swede (or whatever veg you fancy), add 2.5 pints veg stock and 2 bay leaves, a little pepper. After cooking remove bay leaves, put soup in blender. So easy and so tasty.
