Roasted terminalia catappa seed is a specialty of Con Dao island. It is made from the seed of terminalia catappa, a typical tree of Con Dao with a local name of "bang". Many bang trees are hundreds of years old.

The bang seed is processed entirely by hand. There is no fixed recipe. It all depends on the experience and taste of each worker. The bang seeds are divided into smaller batches.

Each batch usually weighs around 2kg, which will take more than 1 hour to roast. The worker who roasts the seeds need to keep the fire low and stir well to avoid burning.

In Con Dao, the bang tree grows everywhere. It is an effective shield against waves and winds. It provides shade for the people of Con Dao. It brings in work for them to improve their income./.
