Dosa Secret Revealed: Science Behind Water Sprinkling on Griddle, Not Just Cleanliness

• Sprinkling water on a hot griddle before making dosa isn't for cleanliness but involves the 'Leidenfrost Effect'.
• The 'Leidenfrost Effect' creates a steam layer, preventing water from direct contact and indicating optimal griddle temperature.
• Water droplets help reduce the griddle's temperature to a controlled level, allowing the batter to spread easily and prevent burning.
• IIT Madras research shows sprinkling water and wiping ensures even heat distribution for uniform cooking and golden crispiness.
• This scientific process is crucial for achieving the perfect, hotel-like crispy dosa.
