METHOD
In a 4 pint/2.2 litre saucepan, melt the butter and cook the onion until soft. Add the potatoes and cook for 2-3 minutes, adding a good pinch of salt and pepper. Pour the warm stock into the saucepan and add the bay leaf. Cook until the potatoes are soft - remove the bay leaf. Chop the watercress and the thyme then add to the saucepan. Cook for a further 2 minutes. Blend together, add the cream and any further seasoning if needed. This soup can be eaten hot or chilled. It is delicious with piping hot croutons on top.
