That cut also is what I do with avocados. Halve an avocado, then do that same pattern on half the avocado with the skin still on. Then just scoop the whole thing out with a spoon. Diced avocado, ready for guacamole. Of course, you'd do it differently if you wanted whole slices for a sandwich or something, but 90% of the time I have an avocado, it's for guacamole.
Just had one of these mangoes for breakfast. Love them. I tried some mangoes in Australia. They seemed like the yellow kind but bigger. Also amazingly good. You could buy them on street corners like people selling strawberries in southern California.
When something good is in season, get all over it.
