This is our first year growing German Butter Ball potatoes and most of them developed this defect but the Yukon Gold and Desiree did not. Any clue why they did this?

Built in bacon bits - I’ll bet that took some serious engineering.

Doesn’t look like insect damage so I am going to guess maybe they were in the ground too long?? Which reminds me I have some potatoes to dig. :)
