Mamidikaya Pappu, also known as Kacchi Kairi Tur Daal, is a traditional South Indian dish made with raw mango and pigeon peas. This tangy and flavorful lentil curry is a perfect combination of the sourness from the raw mango and the earthiness of the lentils. It is a comforting and nutritious dish that is often served with steamed rice or roti.
