My recipe for Guacamole: ask Nicaraguan wife to make it for me :-D
...and luckily, she leaves out the hard-boiled egg from the traditional Nica recipe, yuck.
Jokes aside, when she moved to the US, I introduced her to my Mexicany guac recipe, which she liked more than the Nica one. Over the last few years, with just a few small changes to my recipe, we've developed what many people say is the best guacamole that they have ever had. I've never written it down, but I might do that later and post up here.
One ingredient that we sometimes use is finely ground dried chipotle peppers; the smokey flavor is a nice contrast to the smooth avocados.
rmirandayopo, those are some awesome photos, but sugar and vinegar? I'm intrigued... can you post up your complete recipe?
