I bought a batch of firm mangoes and left them on the counter to ripen. A few have developed dark patches while still feeling hard, and I can’t tell whether they were bruised in transit or whether something is wrong with how they’re being stored.
For people who handle mangoes regularly, what do black patches on mangoes usually indicate before the fruit softens? Is there a way to distinguish a surface mark from damage that has spread inside, or should I cut one open to check?
