Cristobo the only Asturiana born I know is my little Asturiana Mother and she can still make the best Fabada this side of Spain!
Yes, Cubans of Asturian descendents have maintained the traditions even here in the U.S.A., particularly in morcilla and chorizo making. There is a family of Cubans in the U.S. that have maintained the tradition and they sell it here in Florida, they are good, but, in my opinion it tastes a little different than the ones we buy from Asturias, but much better than the Quijote brand.
The family's name is Lugareño,their story began in Asturias, Spain where Lugareño turned their own farm fresh pigs into chorizos, they left to Cuba to Camaguey, then left to Florida in the early 60's. You can buy their chorizos, salchichon, chorizon, and morcillas, in Miami, Orlando and Tampa.
By the way, I joined the forum and it is fantanstic. I have found much information about Aviles, Ribadesella y Villaviciosa. It has certainly made my month, Cristibo, muchisimas gracias.
