Seeni Sambol — Sri Lankan caramelized onion relish

Seeni sambol, literally sweet sambol, is the slow-cooked onion relish that Sri Lankans treasure. Sliced onions are cooked down with chili, tamarind, and Maldive fish until they turn a deep mahogany, sweet and sticky with real heat underneath. It is a building block of lamprais and kottu, and a single spoonful transforms a plate of plain rice. The slow cooking is the whole secret, there is no shortcut to flavor like this, and it is the relish that makes plain rice feel like a celebration.

Chef Emily presents Seeni Sambol

Dark, sticky, and worth the patience

The onions melt into jammy strands that are intensely savory-sweet, with tamarind’s tang and the chilies’ burn arriving after the first sweetness. It keeps for weeks in the fridge and only gets better with time, so a batch is a gift that keeps giving. A little goes a long way, serve it in small bowls alongside curries or spread it on bread. The secret is patience and a heavy-bottomed pan.

Step by stepInstructions

  1. Heat the coconut oil in a heavy skillet or pot over medium-low heat.
  2. Add the onions and salt and cook slowly, stirring every few minutes, for 25 to 30 minutes, until very soft and deep golden brown. Do not rush this.
  3. Add the garlic, chili powder, cinnamon, and cardamom and stir for 2 minutes, until fragrant.
  4. Stir in the tamarind paste, sugar, Maldive fish, and water.
  5. Cook uncovered over low heat, stirring often, for 12 to 15 minutes, until the mixture is dark, glossy, and jammy, adding a splash of water if it threatens to stick.
  6. Cool and store in a sealed jar in the fridge for up to 2 weeks.

💡 Chef tips & storage

Slice the onions as thinly and evenly as you can, and cook low and slow, stirring often, so they caramelize instead of burn. Maldive fish adds umami depth; if you skip it, add a splash of fish sauce.
