Delia's Gratin of Mussels with Melted Camembert recipe. I first sampled this concept in Normandy where the Camembert was used as a topping for oysters. Then back home, I discovered it goes superbly well with mussels too.
Delia's Ragout of Lamb recipe. Neck of lamb is less expensive than many other cuts and, because of the bones, always gives the maximum amount of flavour. This, I think, is an excellent summer casserole.
