1 Wash leeks and chop from base to pale green bit in 1cm rounds
2 Heat a biggish knob of butter and a splash of olive oil in a pan with a lid, add the leeks, S&P, cover and cook very gently for 25 minutes
3 After 15 minutes add a capful of sherry to the leeks and put pasta on to boil (I used farfalle but you can use any shape), when it's done drain and add to leek pan
4 Serve in bowls, grate a good amount of parmesan on top, et voila! Done, supper the easy way.
