The star fruit, also known as the carambola, is a unique fruit that originates from tropical regions. It gets its name from its distinctive star-like shape, with five pointed angles running down its sides. The fruit is typically green or yellow, with a waxy skin and a crisp, juicy texture. While slightly sour when unripe, the fruit transforms into a sweet and aromatic delight as it ripens, taking on a golden hue.

Star fruit season is just around the corner.

While the carambola tree is native to the Northern regions, it is in Hanoi where the fruit truly shines. Typically appearing towards the end of May, the star fruit becomes a common sight in the ancient streets of Hanoi during June and July, sold by street vendors. For Northerners traveling South or elsewhere during the summer, this fruit is a must-have item in their luggage.

Young, unripe star fruit is often seedless and makes for a delightful snack when dipped in salt and chili. It is also commonly used to make a type of Vietnamese salty-sweet dried fruit called “ô mai” or pickled in sugar syrup. As the season progresses, the fruit develops a more pronounced sour taste, making it perfect for cooking. It is used in soups and is particularly famous for its role in a traditional duck dish. When fully ripe and golden, the fruit takes on a milder sweetness, often enjoyed as a snack, especially when dipped in sugar.

Ripe star fruit has a golden hue and a milder sour taste.

The name of this fruit can be quite misleading to newcomers in Hanoi, as it is called “sấu,” which sounds similar to the word “xấu,” meaning “ugly.” However, despite its unassuming appearance, the fruit is incredibly versatile and full of flavor. Generations of Hanoians have also associated the star fruit with first love—a bittersweet experience that leaves a lasting impression, much like the fruit itself.

Selecting the perfect star fruit is no easy task. The best fruits are often plucked from ancient trees lining the streets of Phan Đình Phùng, Tràng Thi, and Trần Hưng Đạo, sold by locals on the sidewalks or in the city’s markets. Currently, the star fruit season in Hanoi is just beginning, and the seedless young fruits are being sold at a premium, approximately 50,000 VND per kilogram, with prices expected to drop as the season progresses.

There are countless delicious dishes made with star fruit.

During this season, young star fruit is often pickled in sugar syrup, resulting in a refreshing drink with a sweet and sour taste. Known for its high acidity, star fruit is believed to possess cooling properties, aiding in detoxification and heat relief. It is also commonly used in dishes like sour soup and muống vegetable soup, adding a distinctive flavor. For a snack, you can try the famous star fruit “ô mai,” available at many shops in Hanoi.
