Ask any Indian “What’s for dinner?” and you’ll hear a story. Food in India is deeply regional, seasonal, and personal. A Tamil Brahmin’s sambar tastes nothing like a Punjabi’s dal makhani . Yet, there’s a shared language: thali (a platter with small portions of multiple dishes), the importance of eating with hands, and the belief that food nourishes not just the body but the mind and spirit.
