It’s not unusual for some potato chips to have green edges. Anyone know what this is?
Chlorophyll.
The Master gets it wrong, then corrects himself, way back in 86:
Are green potato chips poisonous?
Now it used to be that greening potatoes, and sprouting eyes produced potentially toxic levels of solanine, but I think farmers have moved to low-solanine cultivars over the past 40 years.
