The main ingredient of a traditional paella is rice, specifically a variety known as "Bomba" or "Sénia" rice. Originating from the Valencia region of Spain, paella is a beloved dish that combines rice with various ingredients, depending on the version being prepared. The rice is typically cooked in a wide, shallow pan, allowing it to absorb the flavors of the broth and other components like vegetables, seafood, or meats. While authentic recipes may vary, rice remains the essential element that forms the foundation of this iconic dish, celebrated for its vibrant colors and rich flavors.
