There's not a single mention of Americans "dyeing potatoes" in this entire article, except for the title and an allusion to a youtube video explaining how to dye potatoes. That's it. Who comes up with these ridiculous titles? Oh right, robots.
The lack of any photos of anything other than dyed real eggs and an instagram post from a cooking blog showing off their nicely decorated chocolate eggs is also a big tip off.
Potatoes for the Rockefellers, Carnegies, and Morgans, maybe. We have to forage for pinecones and dip them in reddish mud and/or blackish mud if we want anything close to resembling an Easter egg hunt.
