Safrà de muntanya

@Henry: You're right; saffron is one of those "secret" ingredients of paella. The other big secret of a "real" paella is that it should NOT have any fish or seafood in it: it was originally a mountain dish with vegetables and meat (pork and chicken) prepared by the peasants with what was available on site in the fields, and was eaten directly form the "paella" (i.e., frying pan in Catalan) by several people at once using wooden spoons. Later, though, it was combined with other rice dishes from the coast and became the current well-known recipe that includes shrimps, mussels, and other sea-faring beasts. Anyway... thanks for the comment!

@Francesc B.: Gràcies! Jo havia vist les plantetes aquestes per la muntanya sense saber que eren de la família del safrà, fins que la meva companya, que sap d'aquestes coses, m'ho va fer notar... Gràcies pels teus links!
