The custard apple is a green, cone-shaped fruit with scaly skin and creamy, sweet flesh. Thought to have originated in the Andes mountains of South America, it is traditionally grown in tropical areas with high altitudes. It is often eaten with a spoon and served chilled like custard. The custard apple has a sweet taste similar to other tropical fruits, such as banana and pineapple. Rich in fibre, vitamins, and minerals, this unique fruit may help boost immunity, fight inflammation, and promote eye and heart health.
