Dosa Secret Revealed: IIT Madras Professor Explains Science Behind Crispy Dosa

• IIT Madras Professor Mahesh Panchagnula explains the 'Leidenfrost Effect' behind sprinkling water on a hot griddle for perfect dosa.
• Sprinkling water creates a steam layer, preventing direct contact and indicating the ideal temperature for dosa.
• This technique balances griddle heat, allowing dosa batter to spread easily and achieve a crispy texture with a soft center.
• The method, passed down through generations, ensures even cooking and reduces oil consumption by controlling griddle temperature.
• Dosa, a fermented food, is good for digestion, keeps you full, and can aid in weight management.
