About This Recipe
Sri Lankan Seeni Sambol is a real, traditional Sri Lankan dish, known as Sweet Caramelized Onion Relish. Onions slow-cooked with tamarind, chili and Maldive fish into a sweet, tangy, deeply savory relish, a beloved condiment across Sri Lanka.\n\nSeeni sambol, meaning 'sugar sambol', developed as a way to preserve onions through slow caramelization combined with tamarind's sourness and dried fish's umami, becoming an essential condiment for rice and curry meals as well as a popular bread filling.\n\nThe result is a dish worth making on its own merits: it rewards patience with the technique and delivers real, specific flavor rooted in Sri Lankan home cooking, not a generic stand-in for a search term.

Pro Tips
- →
Cook the onions low and slow for the full time — rushing this step means missing the deep caramelization that gives seeni sambol its signature sweet, jammy depth.
- →
Balance the sweet, sour and spicy elements carefully, tasting and adjusting sugar or tamarind as needed.
- →
This relish keeps very well and improves in flavor after a day or two resting.
Variations
- •
A version without Maldive fish makes a fully vegetarian seeni sambol.
- •
Some households add a bit of extra chili for a spicier version.
- •
Use it as a sandwich filling with bread, a very popular way to enjoy seeni sambol on its own.
Storage
Refrigerate leftovers in an airtight container for up to 3 days. Reheat gently on the stovetop or in the microwave with a splash of water or stock to loosen the texture.

Frequently Asked Questions

Why is my sambol too sour or too sweet?
