One of Kolkata's oldest temples dedicated to Goddess Kali, Thanthania Kalibari, has a ritual of offering non-veg prasad 'dab-chingri' (prawns cooked in coconut). It's believed Ramakrishna Paramahansa started this when he offered it while praying for Brahmananda Keshav Chandra Sen's quick recovery. Ramakrishnadev's followers also offered it while praying for his quick recovery when he fell sick.
