From the New York Times.
PAELLA, the classic rice dish from Spain, is considered picnic food — a one-dish meal prepared over a fire at an outdoor party like our hamburger cookout. It is also cooked indoors, but always in a flat steel paellera or in an earthenware cazuela. The main rules are to cook the rice uncovered and, unlike risotto, not to stir once the simmering has begun.
You can make great Paella in a Forno Bravo pizza oven!
