I had a friend in grade school with an allergy who could only eat these Pepperidge Farm “chocolate chip cookies” and the cookies tasted ok to me, but even then as a kid I knew I’d be sticking to dark chocolate given the choice.
I wonder if people with allergies to cocoa can get by unprocessed, organic cacao nibs. Maybe there’s a subset of folks for whom the allergy is the alkali (“dutch cocoa process”) and not the poor ol’ lovable Theobroma cacao itself.
Otoh, this, ouch:

Some people are definitely reactive, Zoiks!
