After going to the tasting at Xain's, and trying to focus on flavor evaluation with all the mangoes I tried there and elsewhere, I realize how much ripeness and preparation affect the flavor perception. It's almost like eating a totally different fruit. The stage you pick it from the tree, the amount of ripening time you give, the way you cut it, the texture of the fruit, skin or no skin, the part of the fruit, the size of the piece, temperature - every single factor can make or break a mango's flavor.
I have had a lot of Maha Chanok in the past and most of them exhibit a funky quality that I struggle with. But yesterday I had a perfectly ripened Maha with good texture, just a little bit firm, and it was candy sweet and intensely flavored in the most pleasant way. It was probably picked slightly underripe but for me that made it better.
I also got to try CeciLove, big thanks to johnb51 who hooked me up. Sweet Tart is the natural comparison, but I have never been overly impressed with Sweet Tart. For me, CeciLove added a lot of mango and background flavor missing in Sweet Cart. CeciLove has that Smarties candy quality up front, with mango, peach, and even a faint coconut flavor providing depth to the sweet and slightly sour interplay. Compared to Sweet Tart, CeciLove has better balance, more flavor, and more enjoyable sweetness.
Xain gave me a big old M-4 to take home, and the completely green fruit softened without ever changing color. I cut a bit off the end to test the ripeness and it was ready to eat. I found the taste very good verging on excellent, but it probably needed a couple more days on the tree. The mango was notably less sweet than the other varieties I've been eating recently. For me, that's not a problem, it just leaves more room for flavor to come through. I love the coconut forward flavor, on top of the nicely balanced citrus and mango tastes. The ripeness throughout the mango varied more than I like - larger fruit can suffer from this. I look forward to tasting more M-4. Properly ripened with the correct flavor intensity it should blow the bloody doors off. As a certified coco-nut, I've already got a tree in the ground.
