Why calling every Indian dish a 'curry' falls short

Comedian Trevor Noah said on his podcast What Now? that he often called Indian gravy dishes curry, only to be corrected in India. Chef Asma Khan said she first heard the word in England in 1992, tracing it to the South Indian word kari, and that every Indian dish has its own name. Food author Sadaf Hussain is documenting 100 Indian curries.
