The leek is a wonderful vegetable currently in season and often overlooked for its more exotic counterparts.  A member of the allium family, but milder in flavour than the onion, like them, they are rich in sulphur and consequently both anti-bacterial and antiviral.  They are also rich in flavonoids which have a cardio-protective effect on the body.  Containing a fibre called inulin, they act as a prebiotic, that is, they feed probiotics and promote good bacteria in the gut, thus helping to maintain a healthy digestive tract.  Leeks provide a good source of folic acid, iron and potassium , as well as lesser amounts of B vitamins, magnesium and calcium.  They are alkalising and have a cleansing or diuretic effect on the body, can help with bladder stones, and may also be used to help regulate bowel movements.  They are anti-arthritic and can also help alleviate the symptoms of gout.  In other words, they are a wonder vegetable.

In terms of cooking with leeks, they are very versatile.  Most commonly used in soups (as part of the stock, or on its own in a vichyssoise), leeks are delicious boiled and served cold, dressed with a vinaigrette.  They also work well with Asian dishes to delicately flavour broths.  They work particularly well with potatoes, ham and cheese, and make theperfect comfort food for wet, cold winter evenings.

My mum used to make this dish for us in winter, and we all loved it.  I suspect it was inspired by a Robert Carrier recipe.  The leeks are blanched and then wrapped in ham, topped with a cheese sauce and baked until bubbling and golden.  It is quite indulgent due to the butter, milk and cheese content, so should be viewed a treat rather than a routine supper..  Make sure you use the full fat versions of all the dairy items to maximise your intake of fat-soluble vitamins, and to really enjoy the taste.  Food that is whole is more satisfying than food that has had its fat removed.
