From Best of Cooking for all Occasions. I took this book out of the library and thought this sounded like an easy way to dress up veal. I have never seen lovage before but it is in the parsley family. There is a cook's tip at the bottom of the recipe that reads: If you wish , substitute plain low-fat yogurt for half the cream in the sauce. In this case, do not bring sauce to a boil after adding the yogurt and cream: heat through over low heat, stirring constantly.
