March 30 was World Idli Day, and what better way to observe it than a get-together to celebrate the south Indian staple delicacy, along with Dosas. Shastha Foods, whose batters have been responsible for an estimated 160 million (and counting, with a vision of a billion by 2030) Dosas and Idlis made all through the US homes and restaurants, commemorated its 20th anniversary on the same day.
