Kala Namak Rice, also known as Black Salt Rice or Himalayan Black Rice, is a variety of rice that is native to the Indian subcontinent. It is distinct due to its association with the traditional Kala Namak salt, which is a type of rock salt found in the Himalayan region. While Kala Namak Rice itself may not be a common rice type, it's often referred to in relation to how it is prepared or served with the special Kala Namak salt.
