Q: There are many recipes where freshly toasted nuts are called for, and that got me wondering--how far can I toast them in advance without sacrificing flavor? If not, how quickly do they lose flavor, and what causes the degradation? Are there any ways to store the nuts to preserve the flavor of freshly toasted? Would freezing and/or vacuum sealing do the trick?
A:
Do toasted nuts quickly lose flavor?
