Tove of Denmark invites you to try her recipe for Arne Riddere (Poor Knights); Katinaki of Greece is preparing Hunka Begendi (Lamb Stew with Eggplant Puree); Shoko of Japan is watching a pot of Charvan-mushi (Steamed Broth with Chicken, Egg and Vegetables). In all, ten girls from ten different countries (including the U.S.) presenting the recipes for a complete meal through the person of a well-known author of cosmopolitan cookbooks. The addenda can be passed over quickly: the introductory Watch-outs and Warnings are rather condescending and quite unnecessary for the youngster with sufficient know-how to tackle these dishes; the letters from the girls which introduce each section provide only a smattering of information; the drawings by Gioia Fiammenghi are pleasantly decorative but not descriptive; the glossary of cooking terms is selective and to the point. But, ah...those recipes! The young cook will need a good butcher and a large budget, as well as patience and skill, but with these she can't miss: Mrs. Knopf has provided exceptionally clear, detailed instructions. For girls who love to cook and their lucky families, a feast fit for international gourmets.
