Ragi, the red millet, is considered to be the favourite food of the goddess down South. In Tamil Nadu, Ragi Koozhu, or porridge balls made of ragi, is a staple “prasadham” in many Mariamman temples (Mariamman is considered to be an incarnation of Kali.) And Koozhu, also called Keppai Kali or simply Kali, is a poor man’s food: inexpensive, nutritious, cooling, rich with iron, vitamin B, protein amino acids, phosphorus, magnesium and potassium. It lowers blood pressure and asthma, repairs skin problems, helps in muscle and bone growth and served especially to young children and the elderly. A staple diet in farming communities, no festival of the goddess is complete without women making ragi porridge in the temples and distributing those to the poor.
