4 free-range chicken breasts, skinned
The trimmings, peelings, etc from your head of celery, chopped
1ltr chicken stock; a good cube will do
Salt and freshly ground black pepper
3-4 sticks of celery, peeled if stringy and cut into ½cm dice
A handful of celery leaves
Put the celery trimmings in a saucepan with the chicken stock, bring to the boil and simmer very gently for 30 minutes, then strain through a fine-meshed sieve into another pan. Put the chicken breasts in the stock, season and simmer for 7-8 minutes.
Next, transfer the breasts on to a plate and cover tightly with clingfilm to keep warm.
Continue simmering the stock until you have about 300-400ml left, add the diced celery and simmer for 5 minutes until tender, then add the leaves and remove from the heat.
To serve, place the chicken breasts in a pasta-type bowl and spoon over the broth.
