Paella is a Valencian rice dish with ancient roots that originated
in its modern form in the mid-19th century near the Albufera lagoon, a
coastal lagoon in Valencia, on the east coast of Spain. Types of paella include Valencian paella (Spanish: paella valenciana), seafood paella (Spanish: paella de marisco), and mixed paella (Spanish: paella mixta), but there are many others as well. Valencian paella is believed to be the original recipe and consists of white rice, green beans (bajoqueta and tavella), meat (chicken and rabbit), white beans (garrofón), snails, and seasoning such as saffron and rosemary.
Another very common but seasonal ingredient is artichoke. Seafood paella replaces meat with seafood and omits beans and green vegetables. Mixed paella is a free-style combination of land animals, seafood, vegetables, and sometimes beans. Most paella chefs use calasparra or bomba rices. All types of paellas use olive oil.
According to tradition in Valencia, paella is cooked over an open fire, fueled by orange and pine branches along with pine cones. This produces an aromatic smoke which infuses the paella. Also, dinner guests traditionally eat directly out of the paellera.
