Santol fruits are round, averaging 4 to 7 centimeters in diameter, and have a slightly flattened shape. The skin is leathery, somewhat fuzzy, and wrinkled, ripening from green to golden yellow, and is sometimes covered in a red blush. Underneath the surface, the thickness of the peel will vary, depending on the variety, and can be thin and fibrous to thick and spongy. Santol fruits also have a translucent to white pulp that encases 3 to 5 inedible seeds. The pulp has a cotton-like consistency and is juicy, slippery, and soft. Santol fruits range in flavor from sour to very sweet, depending on maturity and variety. The sweetest Santol fruits have a candy-like taste with mild peach and apple notes, while in the sour varieties, a strong umami aftertaste may linger on the palate.
Santol fruits are best suited for raw applications as their sweet and sour flavor is showcased when consumed fresh, out-of-hand. To eat raw, the flesh can be sucked from the seeds, but caution should be taken not to swallow the seeds as they are inedible. The flesh can also be sprinkled with salt and spices, consumed as a snack, or it can be soaked in fruit juices and blended into a beverage. In addition to raw applications, Santol fruits can be cooked into jellies, jams, and syrups, canned for extended use, cooked into chutney, or candied as a sweet treat.
Santol fruits are a good source of iron, which is a mineral that can help move oxygen in the blood and fiber, which can help regulate digestion. The fruits also contain calcium, phosphorus, and vitamin C.
