Anyone who has depended on Casserole Cookery (as I have) ever since its publication will cheer lustily at this new volume with 150 new recipes. Packaged and frozen goods have added new possibilities and Mrs. Tracy has made the most of them, using fruit concentrates, mixes, foreign dishes, new ways to glorify the common vegetables, to make best use of economical meat cuts and meat substitutes. She is much more budget conscious, it seems to me, in this volume, using thick cream and butter with greater discretion. I found provocative ideas and plenty of recipes which (on a too, too busy day) I assiduously copied out for immediate use. (No waiting for October 26th!) Occasionally some of the ingredients sounded a bit exotic for the average palate (smoked oysters are not everyone's dish). But all in all, it is another Must for the cookbook shelf. And it should sell more copies of the indispensable Casserole Cookery. Not to be overlooked are the excellent menus accompanying each recipe, suggestions as how to make a reputation for gourmet meals with a casserole as de resistance.
