Cold Serving DishesA whole category of merchandise, from mugs to lunch boxes, pledges to keep foods hot or cool, but past tests at the Good Housekeeping Research Institute have shown these items rarely deliver. When we noticed serving dishes and grocery bags with temperature claims (some promising to keep food chilled for two to eight hours, others saying they'd keep food "cold" or "fresh"), we had to see for ourselves.
HOW WE TESTED We set our climatology chamber to 70°F with 50 percent humidity, then 90°F with 90 percent humidity, to simulate warm and sweltering days. Each dish was filled with cold potato salad, and readings were taken every 15 seconds until temps hit 41°F (one degree above the recommended food-storage temperature). We also loaded insulated bags from the American Bag Company ($20 for five) with refrigerated staples like juice and frozen fare like ice cream, then ran the same test against grocery bags.
