Chettinad cuisine is known for its mix of spices and pulses. It all started with the cuisine and now it has affected anything that is food. Any restaurant in Tamil Nadu has to be christened with 'Chettinad' or it will not sell... this mindset has forced even buttermilk vendors to name their product as Chettinad buttermilk.
Any chicken is Chettinad chicken, even when its prepared in the Chinese way. Even sandwiches are named so ... did sandwiches originate from Chettinad? Companies marketing pulses and grains boast the name ... and so on
The sad part is when my friends order the 'Chettinad' christened dishes and my taste buds refuse to acknowledge that this is the extent of marketing that prevails.
