ANYONE WHO HAS EVER forgotten in mid-recipe how many tablespoons make a quarter of a cup will appreciate the Kitchen Whiz recipe-conversion calculator by Seiko Instruments. It also enlarges or reduces recipes and converts European metric recipes to U.S. weights and measures.
Based on a Massachusetts Institute of Technology patent, the Kitchen Whiz computes cooking times for roasts and acts as a food-preparation timer, temperature converter, clock, calendar and calculator. Powered with two AA batteries, it comes with a full one-year warranty and sells for $59.95. Available at major department stores.
