Poi Sag, also known as “macher matha,” is a traditional Bengali delicacy that features tender and flavorful greens, typically made from the tops of mustard plants. These greens are finely chopped and cooked to perfection in a mildly spiced gravy, with the addition of fish head for added depth and flavor. Poi Sag offers a delightful combination of robust, earthy flavors from the greens and the rich umami taste from the fish head. It’s a cherished dish in Bengali cuisine, best enjoyed with steamed rice for a comforting and authentic meal.
