According to an entry at Global Province, "Blanxart is a small artisanal chocolate company located in Sant Joan Despi, a town just outside Barcelona. Its owners make over 100 types of chocolate and pralines, all by hand, using traditional recipes and select cocoa beans from South America and Africa, which are roasted and blended in the atelier." While their Chocolate Negro Con Almendras can be found at both Dean and Deluca and La Tienda, my wife picked up two bars for me at The Spanish Table in Berkeley.
The taste of the bar is curiously bright. It is packed with small chunks of almond, and the fruit taste of almond (akin to marzipan) nearly overwhelms the acidity of the dark choclate.
