I sometimes struggle to come up with innovative & seasonal vegetable accompaniments; this recipe was devised when I had about 4 leeks left after making Leek & Potato soup, and about half a glass of Chardonnay!! It's a cross between poaching & steaming them in the Chardonnay, you don't want too much liquid. When you are ready to serve the leeks, add your creme fraiche & seasonings and you have an elegant & easy vegetable side dish! Try and use thin leeks rather than the tougher & larger leeks. Measurements are based on 4 people - I have allowed one leek per person, based on the fact that there will be other side dishes & maybe potatoes served as well.
