It was the mango--those "generics", the really pretty yellow, green, red ones. . .
They can be really nasty, The problem is, I have had decent ones, but then I can never get them decent two times in a row. They are stringy and turpentiny in flavor to me and are the first mangos (and almost the last) I ever tasted.
I, like you, like the gold "Alphonso" (big and shaped like the mangos above) or the yellow "Champagne" (or so they are called out here--smaller and shaped more like a kidney bean swimming pool, more narrow at the stem end).
Right now, or very soon, we start getting a mango, almost always a big, green mango, called "Kent" , and it is delicious. I like to purchase them pretty firm, let them get just a little soft so the sweet is balanced by some tart and peel 'em and eat 'em right off the seed. I have made jam from these with great success, using a recipe for peach jam. Local ethnic markets, Chinese, Indian, Middle-eastern, sell them by the case, and they are really good--the best for mangoes and sticky rice!
