In Malayalam 'puli' means tamarind and 'inchi' means ginger. So as you would have guessed, 'puliyinchi' is a combination of tamarind and ginger with some jaggiri added in order to counter the spiciness of ginger. It is used as pickle and the taste is so good with a combination of hot chillies, spicy ginger, sour tamarind and sweet jaggiri.
