Leek recipes anyone?

I have harvested 3kg of leaks this week, mainly from the allotment but also some from the raised beds at home. In addition, we had a lovely fresh supply all through the winter.
With Waitrose selling organic leaks at £4.99 a kilo, that's my answer to anyone who wonders whether it's worth growing your own. (I may have recently defected to Aldi, but I'm still happy to quote Waitrose prices for comparison purposes!)
The car was a tad whiffy on the way home, but that will soon clear. Needless to say, I will be researching leek recipes for this evening's meal.
