This word is from the Spanish phrase pan (de) bonete.
bonnet-shaped dinner roll
also spelled as pan bonete / panbonete
often shortened in Tagalog as bonete
not as ubiquitous as the Filipino roll pandesal
softer than pandesal
Pambonete is frequently served hot with butter melting on its top surface.
Pan de bonete is a common bread in Yucatan, Mexico, and the country of Costa Rica, where the story is that the “bonnet” refers to the hat used by priests during the Spanish colonial era. The Filipino bread’s shape though does not look like a priest’s headwear, and instead is more reminiscent of a chef’s toque.
