I bought this in Ooty market and was told that it is a Nilgiri hills specific vegetable. It is pink on the outside and white inside with two hard black seeds in the upper half of it. It tastes sour, very similar to unripe strawberry.
Now, I'd like to know what the name of this vegetable is and whether it can be used in any dishes. Until know, I've been eating it as a snack, just like I would any other bite sized food.
