While the usefulness of refrigerators explains their prevalence, it does not explain their size. Most people would agree that fresh food tastes better than anything that’s been kept in a refrigerator for even a short amount of time. So why then would anyone want a weeks’ worth of perishable food stored in their kitchen at one time? Are Americans slaves to convenience? While our large refrigerators do limit the number of shopping trips we have to take, they also make it possible for us to consume a much greater variety of foods than we ever did without them in our kitchens.
