THIS IS SO GOOD! My sweetie and I prepared this last night and enjoyed it thoroughly. It was so delicious. The leeks disappear and flavour the lamb sauce very lightly. The accompanying yogurt sauce is lovely drizzled over the meat sauce. Very very nice. This recipe is originally from James McNair's favorites with some slight adaptations. In his cookbook, this is served with stuffed leek pasta, whereas we had it with fresh linguini and it was wonderful.
