Arroz con pollo is Spanish for "rice with chicken."
Saffron, the world's most expensive spice, is the aromatic stamen (threads in the center of the flower) of a certain crocus. A single pound of saffron requires the stamens from 80,000 crocuses. Saffron is sold in minute quantities, often in little clear glass or plastic vials. It's best to buy it in whole threads rather than ground so you can be sure of what you're getting (ground mixtures may be adulterated with inexpensive substances of a similar color). Because a little goes a long way, saffron is affordable for occasional use. Its flavor is distinctive. Turmeric, an often-suggested inexpensive substitute, adds similar color but cannot match the flavor of saffron.
