Black peppercorns are dried fruits of Piper nigrum, valued for piperine pungency and volatile aroma; whole peppercorns season Peter Kuruvita's lime pickle.
Modern method
Lime pickle
Peter Kuruvita’s published lime pickle stuffs 20 limes with rock salt, then simmers them in vinegar, sugar and chilli before a two-week rest.

Peter Kuruvita’s 2009 cookbook places this recipe among Sri Lankan chutneys, sambals and pickles. A Gourmet Traveller editorial page credits Kuruvita and Flying Fish but changes two listed amounts. Neither publication dates the food’s origin.

The book directs jars to stand in a cool, dark place for at least two weeks and says the liquid may not initially cover the limes. It specifies no jar-closure step, validated storage process, acidity endpoint or after-opening guidance.
Hazard sourceThe book’s two-week rest and cool-dark storage directions are not a validated shelf life or room-temperature safety claim.
No numerical acidity endpoint, measured simmer temperature, after-opening guidance, or qualified process review is established.
Broader lunu dehi context; the article does not locate Kuruvita's exact formula.

Independently re-inspected 29 October 2026: direct HTTP download succeeded after browser timeout. Eight-page publisher sales sample; recipe on PDF page 6, printed page 11. Its measured formula and seven saved stages are supported; the book specifies no sealing or other jar-closure instruction. Preserve unspecified closure rather than borrowing sealing from the separate Gourmet Traveller adaptation.
The source does not specify vinegar strength, measured final acidity, a validated preservation or shelf-life process, or after-opening controls. Its initial incomplete liquid coverage and at-least-two-week cool-dark rest are recorded culinary directions, not established safe storage limits.
