When I interviewed Arun Kapil of Green Saffron for the podcast, he casually mentioned “the very unfortunate cumin incident”. Even though I had never heard of such a thing, I didn’t pursue it at the time because it seemed too much of a diversion. In essence, someone, somewhere put peanut shells (and almond shells) in ground cumin (and ground paprika) not knowing (or caring?) that these allergens could hurt someone half a world away.
You can see why someone extolling the quality of their spices would be keen to distance themselves from tainted cumin.
I did some digging, and wrote up what I discovered in more detail over at Eat This Podcast.
