Panther (poached in a tea garden in Assam, India, long ago), red ant egg curry (Assam), fried fish intestines (Assam), water monitor (Assam), alligator (in USA), horse (in France), kangaroo (in Germany), haggis (in Scotland) come to mind, besides the usual stuff. All animal organs are fair game. Cleaned and deep-fried fish intestines, mainly from varieties of large carp, is a very popular delicacy in Assam and a particular favorite of mine. Latest new to me experiment was with silkworm pupae, boiled and then deep fried. Goes very well with mild rice beer, crunchy on the outside and like melted cheese on the inside, with a surprisingly prawn like flavor.
