What does "picones" mean?

Question

I'm looking at a Mexican grocery store ad which lists a round loaf of bread and describes it as " Concha Grandes o Picones"

Answer 1

Interesting.

I found this, which says this is a local bread from Guadalajara.

The funny thing is, as happens oftentimes, in other countries / regions, walking into a bakery asking for "picones" or "concha grandes" could get you is SOOOO much trouble!!!
