Right now, your refrigerator’s door bin might be home to some almost-off milk, a scattering of garlic bulbs and a jar of relish from 2022. Now, Unilever has actually made something useful for you to put in there: a “Smart Jar” that tells you if your fridge is at the right temperature.

In 2019, the CPG’s then-chief executive (CEO) Alan Jope said it would offload brands that lacked purposeful messaging. In 2021, Hellmann’s mayonnaise took up the cause of fighting food waste under the banner of “Make Taste, Not Waste.”
