I am desperate for a recipe. In the 70's there were booklets called the Grand Diplome Cooking Course and in one of the booklets was a recipe for Leg of Lamb, which you marinaded for three days with vegtables. Someone stole the booklet and I have been trying to find the booklet or recipe for years. If anyone knows where I can get the recipe or booklet, I would greatly appreciated. It sounds corney but my father is 87 and he has never forgotten that dinner and I would love to be able to make it for him. Thank you so much for any information yu might have. Best regards, Siobhan
