When I first moved to San Diego, avocado was synonymous for Hass - I wasn't really even aware that there were other kinds. San Diego is avocado central, though, and I've since broadened my exposure to different varieties of the tasty fruit.
Pictured above is this weeks haul from our farmers market. The one on the left is a Nabal. We hadn't heard of the variety before, but we had some for breakfast this morning (with tomato on toast) and it was really, really good - great flavor and super-creamy. The one in the middle is a Fuerte - we've been getting nice versions of these for several months, but they're more of a spring crop and this is the last of them. The big guy on the right is a Reed - I bet we can make a good-sized batch of guacamole with that one alone!
