I dont know what the 'real' spaniard name for it is, in my country (Colombia) we call them chorizos... BUT there's 2 types of it... the delicious and expensive one thats cured which comes from spain and theres another type we also call chorizo which is more like a regular sausage you find in US delicatessens.
The one im talking about is the type that you hang on a wall for days after you buy it, the meat cures as the oils inside drip out and even the thinnest slice carries SO much flavor its just not funny.
It looks a lot like the one in your picture too.
