If your house is anything like mine, you’ve got a kitchen cabinet filled to the brim—no, overflowing—with plastic food containers. Maybe some are ones you’ve bought expressly for the purpose of storing leftovers or decanting dry goods, but chances are you’ve got some (or in my case, many) that originally served as vessels for that curry you ordered for takeout, or the olives you bought from your weekend farmers market. More often than not, these take the form of so-called “deli containers”—you know, those clear cylindrical plastic tubs that come in eight ounce, pint, and quart-sized varieties.
