Saffron (use) the liquid phase; powdered saffron does not require this step. The soaking solution is then added to the hot cooking dish, allowing even colour and flavour distribution, which is critical in preparing baked goods or thick sauces. Threads are a popular condiment for rice in Spain and Iran, India and Pakistan, and other countries. Two examples of such saffron rice is the "zarzuela" fish-seafood stew and "paella valenciana", a piquant rice-meat preparation. It is essential in making the French "bouillabaisse", which is a spicy fish stew from Marseilles, and the Italian "risotto alla milanese". The saffron bun has Swedish and
Saffron action, splits picrocrocin to yield D–glucose and a free safranal molecule. Safranal, a volatile oil, gives saffron much of its distinctive aroma. Safranal is less bitter than picrocrocin and may comprise up to 70% of dry saffron's volatile fraction in some samples. A second molecule underlying saffron's aroma is 2-hydroxy-4,4,6-trimethyl-2,5-cyclohexadien-1-one, which produces a scent described as saffron, dried hay-like. Chemists find this is the most powerful contributor to saffron's fragrance, despite its presence in a lesser quantity than safranal. Dry saffron is highly sensitive to fluctuating pH levels, and rapidly breaks down chemically in the presence of light and oxidising
