Sabut Masoor, also known as whole red lentils, is a type of lentil that is typically used in South Asian and Middle Eastern cooking. It has a distinct reddish-brown color and is shaped like small oval discs. Unlike split masoor dal (where the skin is removed), sabut masoor retains its outer skin, making it slightly more robust in texture when cooked.

Sabut masoor is rich in protein, fiber, and minerals like iron and magnesium. It is also a good source of folate and B-vitamins. It's a popular choice for vegetarians and vegans due to its high protein content.

Sabut masoor requires a bit more cooking time than split lentils. Typically, it is cooked by boiling or pressure cooking, and it can be spiced with ingredients like turmeric, cumin, ginger, garlic, and coriander to create flavorful dishes.
