Description
Ambarella is the fruit of Spondias dulcis, a tropical tree in the Anacardiaceae family — the same family as the mango and the cashew. The fruit is an oval to oblong drupe, commonly 4–10 cm long, with a thin but tough skin. It is eaten at two very different stages, which is the key to understanding how to use it.
When green, ambarella is firm, crisp and sharply sour, with a clean tartness that brightens salads, pickles and sambols. As it ripens the skin turns from green to a bright orange-yellow, the flesh softens, and the flavour shifts toward a sweet-tart, lightly tangy and fragrant taste — the "golden apple" that is enjoyed fresh, in juice or in preserves.
One trait marks ambarella apart from most fruits: its stone. The single central seed sits in a woody core whose surface sends tough, spiny, fibrous strands radiating outward into the flesh. These fibres are barely noticeable in a crisp green fruit but become conspicuous as the fruit softens, making a fully ripe ambarella slightly fibrous and harder to slice cleanly.
Origin & History
Ambarella is native from Melanesia through Polynesia, and was carried across the tropics by Austronesian seafarers as a canoe plant, then spread further in colonial times. It was introduced into Jamaica in 1782 and again ten years later by Captain Bligh, and from there spread through the Caribbean, where it is called golden apple or June plum. Today it is grown widely in South and Southeast Asia, the Pacific, and tropical America, and in many places it has become so thoroughly naturalised that it is treated as a local fruit.
In Sri Lanka the fruit is a familiar home-garden sight. Green ambarella, soaked in vinegar with chilli and spices, becomes acharu — a lively, sour-sweet pickle sold at hawker stalls and eaten as a snack. Across Southeast Asia the same idea appears under different names: green slices are tossed into rujak salads and made into sambal pickles.
Uses
Culinary
- Green, raw: Sliced thin and eaten with chilli, salt and sugar, or tossed into sour salads such as Indonesian rujak
- Pickles and sambols: Steeped in vinegar with chilli — Sri Lankan acharu — or made into sambal pickles
- Curries: Green ambarella adds a sour note to curries
- Ripe, fresh: Flesh cut away from the stone as a sweet-tart snack or for fruit salads
- Juice and preserves: Stewed into juice, jam and jelly
- Leaves: Young steamed leaves are eaten as a vegetable
Nutritional Benefits
Ripe ambarella flesh is mostly water — around 60–85% of the edible portion — with modest carbohydrate (much of it sugar in the ripe fruit, about 8–10.5 g sucrose per 100 g), a little protein (0.5–0.8 g) and fat (0.3–1.8 g), and useful fibre (0.85–3.6 g). The flesh is described as a good source of vitamin C and iron.
As with any fruit, ambarella is best understood as part of a varied diet: the green fruit as a bright, sour counterpoint and the ripe fruit as a juicy, low-fat snack. Its most distinctive quality is culinary rather than medicinal.
How to Prepare
For the Green Fruit
- Choose: Pick firm, unblemished green fruit with no soft spots.
- Wash: Rinse and pat dry.
- Slice: Cut wedges away from the central stone on a stable board. Even green fruit can have a tough, fibrous core; do not force a knife through it. Discard the stone and any hard fibres.
- Season: Toss with chilli, salt and a little sugar, or steep in vinegar with chilli for acharu.
For the Ripe Fruit
- Choose: Look for a golden-orange skin that yields slightly to pressure.
- Wash and slice: Because the stone's fibres grip the flesh, cut wedges away from the core rather than slicing straight through.
- Separate: Peel the flesh from the fibrous stone and discard the stone.
- Eat or cook: Enjoy fresh, or add to juice and preserves.

- Small-fruited form: A distinct form with small, sour but edible fruit occurs in New Guinea.
Fun Facts
- Ambarella shares its family tree with the mango and the cashew — and even has a similar sweet-tart spirit when ripe.
- The fruit's fibrous stone is its signature: spiny strands that radiate into the flesh, a feature that sets it apart from its close relatives.
- One tree can carry bunches of a dozen or more fruit, and it fruits more or less continuously in the humid tropics.
- Its many names — golden apple, June plum, Jew plum, ambarella — tell the story of a fruit that crossed oceans and became local everywhere it landed.
