This topic is driving me sane! Aceitunas rellenos de anchoas, certainly! Aspergas blancas, tambien! Mejillones en escabeche, boquerones or anchoas, etc., etc. Granted, a lot of those things are available in the U.S., but are very pricey. One tip: Check out your local 'dollar' store. I have found Mejillones and Portuguese sardines in one nearby.
Orujo de Liebana (even a cousin who lives in Galicia asks me to bring him Orujo de Liebana when I'm coming from Cantabria) and vino origen de Pontevedra (Albariño or Rosal), and Manzanilla from Sanlucar de Barrameda. In July, I brought back 2-tins of Chocolate (brand name Paladin) to make hot chocolate that is so thick & rich it must be sinful.
To the best of my knowledge, the Albariño or Rosal or Manzanilla wines are not available at any of the duty free shops in aeropuerto de Barajas. Nor is the Orujo de Liebana or any other Aguardiente (as they are called, generically).
