A mass of rocket in the garden at present and I wanted to use most up before it flowers and starts to set seed everywhere so...
Cut your potatoes into rings about half an inch wide and place in a sauce pan off water and a little salt.
Bring to the boil and simmer on a low heat until the poatoes are cooked.
Add a large bunch of rocket and some stock and reheat for five mins or so to cook through the rocket.
Blend until it is smooth and push through a sieve.
Reheat to reconstitute and adjust the seasoning.
Serve with a scattering of chopped rocket.
