And for the folks who disdain the West Indies type avocados, i don't get the indignation. Do they get bent out of shape over plantains? Do they expect granny smith apples to taste like golden delicious?
Treating Haas avocados as THE avocado is like treating Dwarf Cavendish as THE banana. All Dwarf Cavendish and all Haas and all Golden Delicious are each clones. If some virus or fungus or whatever becomes particularly deadly, we could loose all commercial Cavendish bananas. Haas could go the same way. Admittedly, i've no idea if avocado trees are more robust than bananas, or if bananas have some particularly virulent agents.
Back to West Indies type avocados, i grew up with them. My grandmother lived in Homestead Florida, and her second husband ran some of the large commercial farms. When we saw them, they would bring or have the large avocados and gleaned field ripened tomatoes. With the addition of bread, salt, pepper, and lime juice we would have delicious sandwiches. We didn't have guac made from them, but cubes tossed in salads.
