The primary ingredient in traditional Spanish paella is rice, specifically short-grain varieties like Bomba or Senia rice. This dish originates from Valencia and is known for its rich flavors and vibrant colors. The rice is typically cooked with saffron, which lends the dish its characteristic yellow hue, along with a variety of other ingredients, which may include seafood, chicken, rabbit, and vegetables. Cooking paella involves a specific technique where the rice is allowed to absorb the flavors from the ingredients while developing a crispy bottom layer known as "socarrat." Paella is celebrated both in Spain and internationally.
