COOKERY Simon is the owner of Omaha Steaks, the well-known mail-order source of high-quality beef, and he and Harrisson are also the authors of The Steaklover's Companion. Their new collection features recipes for beef cuts other than steak, although a few steak recipes did creep in. There are classics like Beef Wellington and more contemporary dishes such as Thai Meatballs with Spicy Peanut Sauce, as well as a few recipes from James Beard, a longtime consultant for Omaha Steaks. Bruce Aidells and Denis Kelly's big The Complete Meat Cookbook (LJ 12/98) includes lots of beef dishes along with recipes for other meats, but beef is America's favorite meat, and larger collections could add Simon and Harrisson's book too.; 256 pg.-
