Unveiling the Star Apple: The Real 'Milk Fruit'
For many, the idea of a fruit containing a milk-like substance is a bizarre concept. However, this is precisely the defining characteristic of the star apple, scientifically known as Chrysophyllum cainito. Native to Central America and the Caribbean, it is now widely cultivated across tropical regions, including Southeast Asia and South Florida. Its names in different languages often reflect this milky quality; for example, in Vietnam, it is called Vú sữa, which translates to 'breast milk'.
When a ripe star apple is sliced horizontally, a radiating star pattern is visible in the pulp, which gives the fruit its common name. The edible part is the soft, jelly-like pulp, which can be green, white, or purple, depending on the variety. This pulp is creamy, sweet, and has a distinctive milky flavor that is often compared to a mix of condensed milk, custard, and tropical fruits.
The Science Behind the Milky Sap
The milky sap of the star apple is a type of latex, which is a common feature in plants of the Sapotaceae family to which the star apple belongs. This latex is most concentrated in the fruit's thick, inedible skin and rind. While the milky sap within the edible pulp is sweet and pleasant, the latex in the rind is quite sticky and astringent. This is why the fruit should not be eaten directly from the skin; instead, the creamy flesh is typically scooped out with a spoon. Chilling the fruit can help to minimize the stickiness of the latex and enhance the flavor.
How to Eat and Enjoy Star Apple
To properly enjoy a star apple, it's best to eat it chilled. Slice the fruit in half and use a spoon to scoop out the sweet, gelatinous flesh, being careful to avoid the inedible skin and core where the sticky latex resides. The fruit can be enjoyed in a variety of ways beyond eating it fresh:
- In fruit salads: Its unique texture and flavor make it a great addition to tropical fruit salads.
- In desserts: The pulp can be blended into sorbets, ice creams, or parfaits.
- In beverages: It can be used to make refreshing milkshakes or mixed with other fruit juices to create a flavorful drink. A notable Caribbean drink called 'matrimony' is made by combining star apple pulp with sour orange juice and condensed milk.

Conclusion
The star apple is a truly special fruit that perfectly answers the question of which fruit has milk inside. Its creamy, naturally sweet pulp is a unique delight for the palate, and its origins in tropical regions have made it a culinary staple for many cultures.
