Yesterday at the farmer’s market I bought two half-pints of berries, one each of blueberry and raspberry.

By the time I was home, the berries had made a very nice paste. Oops: I’d spent too much of my attention making sure I didn’t smash the tomatoes, which is what I messed up last week.

Surely someone could construct a plastic clamshell with two separate compartments, one for each half, into which berries or other small produce items could be placed for safekeeping. It would need to be dishwasher-safe, and very lightweight. For extra points it could fold flat and use a tensegrity structure with soft panels, so I don’t feel like such a doofus toting the thing around the market.
