How to Enjoy Them
The flesh of custard apples is delicious, but the skin and seeds are not edible. Simply cut the fruit in half, take the seeds out and discard them, and scoop the flesh out with a spoon. Or, you can spit the seeds out as you enjoy the fruit.
The flesh can be added to ice cream, juices, smoothies or yoghurt for a delicious dessert. Or, pulp it and use it in custard to add a unique twist to your creamy pudding. It goes particularly well with vanilla, but fresh lime also enhances its sweet creaminess. Because its flavour has nuances of banana and pineapple; it is refreshing and has a distinctly tropical twist.
Grow Your Own Custard Apples
Custard apple trees are beautiful additions to your garden. They need a sunny spot with good airflow and soil that drains well. They don’t do well in areas where the water accumulates in the soil around them. When left unpruned, they can reach a height of between 3 and 6 metres. With some mulch and an average amount of water, they can thrive beautifully and produce an ample yield of tasty fruit.
