Unroasted curry powder, known as "Amu Thuna Paha" (literally "raw three-five") in Sinhala, is a fragrant and distinct spice blend used in Sri Lankan cuisine. Unlike its roasted counterpart, which has a deep, smoky flavor, unroasted curry powder is celebrated for its fresh, vibrant, and aromatic qualities. It's an essential ingredient for creating lighter, milder curries. Typically added at the beginning of the cooking process to infuse the dish with its characteristic aroma.
