No, black lentils and horse gram are different legumes.
Black Lentils (Beluga): Small, round, dark lentils with a firm texture and mild, earthy flavor. They provide protein, fiber, and iron.
Horse Gram: Larger, oval, brownish-grey legumes with a harder texture and slightly bitter taste. They provide protein, fiber, and calcium.
While both are nutritious, they differ in size, color, texture, flavor, and culinary uses.
