One of them have already fully ripen and get fallen.
The others need about two days to get fully ripe and ready to be eaten.
There's a traditional way to make the fruit ripe fasten.
Keep the fruit in the rice box, put the fruit above the fresh rice, and one or two days later the fruit will fully ripen.
We put three of four sugar apples that we have in to the rice box.
And two days later we get fully ripen fruit.
This a favorite fruit in our family.
Look... My little one took any pieces of the fresh, juicy and sweet flesh soon, as soon as I split the fruit.
Just enjoy the home grown fruit.
