What common additive is frequently incorporated into coffee grounds for South Indian filter preparation?

Answer

Chicory

A distinguishing element of many traditional South Indian coffee preparations involves blending the roasted coffee grounds with chicory root prior to brewing. This additive serves several functions: it contributes a characteristic, slight bitterness that balances the subsequent sweetness, deepens the overall color of the final product, and helps maintain the consistency of the highly concentrated decoction derived from the apparatus.
