Real guacamole, I've been told, is made in a molcajete, a large mortar and pestle. I don't have one, so I settled for my regular mortar made from Swedish marble. Works well, too. (It's just a little small.)
I did some variation on this recipe, and served with taco-spiced ground meat on blue corn chips, finally available in Sweden! The brand is Buffalo Ranch and while they're not as thin as restaurant-style tortilla chips, I liked them. Beware though, they have very little salt and some have reported to find them flavorless.
