Chicharrón is a trendy tapa that is expanding throughout Spain and is known as the «special.» The etymology of chicharrón is uncertain, although many of us would like it to come from «chicha» and «ron,» it is most likely that the word «chicharrón» itself (fried pork rind) comes from the onomatopoeia «chich-» (the sound that chicharrón makes when fried).
