Doi Ilish is a traditional Bengali dish made with Hilsa fish cooked in a rich and creamy yogurt-based sauce. The dish is known for its delicate flavors and melt-in-your-mouth texture. The Hilsa fish is marinated in a mixture of spices and then gently simmered in a sauce made with yogurt, mustard paste, and a blend of aromatic spices. The result is a dish that is tangy, creamy, and full of flavor. Doi Ilish is typically served with steamed rice or pulao, making it a perfect choice for a special occasion or a festive meal.
