Sri Lankan Seeni Sambol (Caramelized Onion Relish)
Sweet, spicy Sri Lankan caramelized onion relish with Maldive fish — the essential condiment for every rice and curry table.
About This Recipe
Seeni sambol (sweet onion sambol) is one of Sri Lanka's most indispensable condiments — sliced onions slow-cooked with Maldive fish, dried chilies, curry leaves, and a touch of vinegar and sugar until deeply caramelized and jammy. It's simultaneously sweet, smoky, spicy, and umami-rich, transforming any simple plate of rice and curry into something special. Every Sri Lankan cook has their own version.

Pro Tips
- →
Low and slow is the only way — rushed sambol won't caramelize properly.
- →
It should be very thick and jammy — a spoon should leave a track.
- →
The sweetness and sourness should balance — taste and adjust before finishing.
- →
Taste and adjust salt at the very end — flavors concentrate as liquids reduce, and a final pinch of flaky salt sharpens the whole dish.
Variations
- •
Make fully vegetarian by omitting Maldive fish
- •
Add a little piece of pandan leaf
- •
Include a cinnamon stick while cooking for extra warmth
- •
Vegetarian: swap the protein for roasted king oyster mushrooms, smoked tofu or cooked chickpeas — adjust seasoning slightly upward to compensate.
Storage
Refrigerate in a sealed jar for up to 2 weeks. Flavor improves with time.
History & Origin
Seeni sambol is one of Sri Lanka's most celebrated sambols, appearing on every important table. The name 'seeni' means 'sugar' in Sinhala — referring to its characteristic sweetness. It's been part of Sri Lankan cooking for generations and is considered essential to the national cuisine.
Frequently Asked Questions
Can I make this without Maldive fish?
Yes — it will be vegetarian but equally delicious. The umami will be slightly less deep; add a pinch of MSG or extra salt if desired.
How do I know when it's done?
The sambol should be very dark brown, almost black, and very thick. A spoon dragged through should leave a clear track.
Can I make this ahead of time?
Yes — most of the components can be prepared up to a day in advance and refrigerated separately. Reheat gently and assemble just before serving so textures stay distinct.
What can I substitute if I don't have all the ingredients?
Stay close to the role each ingredient plays: swap aromatics for similar ones (shallot for onion, lime for lemon), and keep the fat-acid-salt balance intact. Spice blends can usually be approximated with what's in the cupboard.
