Shatkora

Citrus macroptera · Assam citrus

The citrus of the hills — a rind, a curry, and a whole diaspora’s idea of home.

What it is

Shatkora is a semi-wild citrus with a thick, rugged, yellow-green rind and a sharp, bitter-sour scent somewhere between grapefruit and lime. It is the rind and pith that are used, not the pulp — the pulp is too bitter and sour to eat. Sliced into a curry, the rind softens and releases a fragrance that is unmistakably its own.

Where it comes from

It grows in the hills and haors of Sylhet in northeastern Bangladesh, and across the border in Meghalaya and Assam, on thorny trees that reach several metres. It travelled with the Sylheti diaspora: much of Britain’s “Indian” restaurant trade is Sylheti in origin, and shatkora — sold frozen in UK grocers — is one of the flavours that came with them.

What it's called

Shatkora · satkara · hatkora (Sylheti). Botanically Citrus macroptera, sometimes called the wild orange.

In the kitchen

The rind is sliced and added part-way through a slow meat curry — classically beef (shatkora mangsho), also mutton, goat and fish — where it cuts the richness with a citrus-bitter edge and once helped preserve the dish before refrigeration. A little goes a long way; too much, or an over-bitter fruit, turns a curry sharp.

What we know about the claims

No notable health claims beyond the vitamin C and volatile oils of any citrus rind. It is a flavouring, valued for aroma and acidity, not a remedy.

Choosing and buying

Sold frozen, whole or sliced, in UK South Asian grocers serving Sylheti communities, and increasingly in the US. If you can’t find it, the rind of a firm grapefruit is the accepted substitute — not identical, but the closest thing to its bitter-citrus register.
