Seeni Sambol achieves its signature depth by slowly caramelizing the onions over moderate heat, allowing their natural sugars to develop without burning. The aromatics, cardamom, cloves, cinnamon, and pandan, lend layered fragrance, while tamarind and sugar balance heat with tangy sweetness. Stir gently but regularly once the tamarind is added to prevent sticking. Store in an airtight container at room temperature for up to one week, and use as a vibrant accompaniment to rice dishes, dosas, or grilled meats. Seeni Sambol is a staple accompaniment to Sri Lankan breakfast, like egg hoppers (appam), string hoppers, roti, or even bread and butter. It's a deeply flavourful, versatile, and long-lasting condiment.
