Dr. Ledesma emailed me back that Fairchild Farm no longer has a fruit stand. =(
Tried Nectar of Neptune and Florigon today.
These mangoes looked a lot alike. Taste was similar as well. FG was mild in flavor and smooth, NN definitely had more taste to it. NN had just a little tartness to it. Texture was great on both mangoes, no fiber noticed except tiny bit on the seed. NN had a more yellow flesh, while Florigon was darker/more orange. Like NN better.
While I've had Nam Doc Mai before, never tried green until this batch. Tart and crispy. Similar to the Chao Savoy in ways, but liked it better. They both are good (if you like tart and crispy), and could see mixing them up in a green papaya salad. My daughter liked green ndm slices with cinnamon, which was pretty good.
