Given the background description of some cooking related query, summarize the question into a title

Ex Input:
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?

Ex Output:
Do toasted nuts quickly lose flavor?


Ex Input:
Currently there is a question about magnetic stripes vs wood blocks, but I was wondering what the general concensus is regarding knife sheaths (like this one) They seem great if you only have a couple knives -- they don't require counter space and aren't at risk of causing accidental harm by falling off a wall. What are the pros and cons of using these instead?

Ex Output:
Storing knives in knife sheaths


Ex Input:
I have 5 - 6 lbs of sauerkraut in a crock with a water vacuum seal. I read that the first 24 - 48 hours are crucial to the success of the kraut. I also read that the kraut should develop its own liquid during this time, and that one can pour boiled water on top if it doesn't. However, I also read that it shouldn't be disturbed for a fairly long period of time. I am a bit confused. Should I check on the progress after a few days, or not?

Ex Output:

How long should I wait before I lift the lid of my sauerkraut crock?
