What is "kata-kat"

Kata-kat or tak-a-tak '''کٹاکٹ ''' is a special meat dish originally from Karachi in Sindh, but now very popular throughout Pakistan. It is made from Offal ( i.e. a mixture of various meat organs), including testicles, brain, kidney, heart, liver, lungs and lamb chops in butter. The dish's name is an onomatopoeia from the sound of the two sharp blades that hit the griddle as they cut up the meat. It is still an open question whether the correct name is kata-kat or tak-a-tak.
