Elephant apple
Dillenia indica · ou tenga · chalta
The sour giant of the eastern river kitchen.
What it is
Elephant apple is a large, hard, greenish fruit with a fibrous, intensely sour flesh — too astringent to eat raw, but prized as a souring agent. Sliced into a curry, it lends a clean, bright acidity quite its own.
Where it comes from
It grows in the forests and floodplains of the eastern reaches — Assam, the northeast, and the River Delta's Assam fringe — where it sours the region's fish curries. It is the tenga (sour) in an Assamese-style fish tenga.
What it's called
Elephant apple · ou tenga (Assamese) · chalta (Bengali). Botanically Dillenia indica.
In the kitchen
Sliced into sour fish curries (tenga) and dals for a clean acidity, and made into chutneys and pickles. It is a souring agent used to taste — the eastern counterpart to the tamarind and shatkora of neighbouring kitchens. Kokum or tamarind stands in where it can't be found.
What we know about the claims
The fruit brings fibre and the tartness of any sour fruit; used as a souring agent, it is a flavour, not a health food. No caution beyond its inedible-raw sourness.
Choosing and buying
Rare outside the region; occasionally frozen in South Asian grocers serving eastern communities (UK and US). Kokum or tamarind is the practical substitute for its souring role.
