How do Indian cuisines reflect the principle of unity in diversity?

Indian cuisines reflect the principle of unity in diversity through the variety of regional dishes, ingredients, and cooking techniques across the country. According to the class 6th social science NCERT, while the basic food staples like rice, wheat, and lentils are common throughout India, the way they are prepared and served varies widely from region to region. For example, the use of spices, cooking methods, and flavors differ between North Indian curries and South Indian sambar, yet both represent Indian culinary traditions. This diversity in food highlights the cultural richness of India while demonstrating how different regions contribute to a unified gastronomic heritage.
