I bought a mango this morning that seemed to be ripe; at least it was the ripest of the bunch. I'm somewhat acquainted with picking out red/green mangoes, but this was my first exposure to yellow mangoes, and I apparently chose poorly.

After slicing up the whole thing, I realized my mistake, and as it is, the fruit is so sour it is inedible.

If it were a lesser fruit (say, a nectarine), I might just toss it, but I'm trying to be resourceful, and mangoes are not inexpensive around here, so I'd like to make use of it. What uses are there for an underripe mango? I thought of simmering it with milk and a little sugar, but I can only guess as to how how things would turn out.
