Why does it matter which size? Does it depend on the dish? How many people you're feeding? Cost? That's just what I was wondering.
LOL I may not fool with it past the first time either. I don't make it that often cause I can't control myself when I have it. Best guac I ever had was at a place in Puebla, Mexico. I wouldn't call it chunky, but there was something in it that provided a bit of crunch almost. Can't describe it. But it was fantastic.
our original recipe that we got from one of my wife's friends had cucumber in it. we only made it that way a couple times. we have made other alterations to it to make it our own. nothing real fancy. just the basics, but so good.
