How can I keep saffron fresh for longer? We don't use saffron that often. The last batch we got went stale. Is there anything I can do to preserve it for longer? (For example, our spice rack gets a lot of direct sunlight, is that bad?) How long can I expect it to last?
There are special glass jars made to protect herbs from damaging uva/b rays, proven to maintain freshness.  Granted, these little jars are designed for a "different" kind of herb, I, on the other hand, use them for my ultra expensive, direct from the middle east saffron.  Keep an open mind and enjoy your saffron!!!
