We had ten full-grown avocado trees on our property when I was a kid. Guacamole was free-flowing and never ever made with sour cream or mayonnaise, or any other filler. While I wholeheartedly appreciate how fortunate we were to live in a house set amid so many fruit-bearers, it did make me a bit of an avocado purist. Not to mention a full-blown guacamole snob. So when one of my sweet nieces offered to make me a guacamole dip with cottage cheese, I tried very hard to keep an open mind, as I braced myself for the impact of something that could taste very wrong.
