Just as the English created a Madras Curry to their liking, the French who colonized the Pondicherry area of eastern India took a liking to the local flavours and made this version their own. A larger-than-usual leaning towards dried onion and garlic, and the freshness of curry leaves, makes this blend mild and a little sweet so it is a perfect starter curry for younger or more sensitive palates.
This curry works well with firm fish fillets, and adjust time accordingly.
