Q: Growing up, I remember my grandparents used to send me out to get potatoes and carrots out of "the storage box." This box was full of sand that had been heated up to kill bacteria (I believe). Once cooled, the potatoes and carrots were buried for later use during winter months.
The question is: Is this method still used? And if so, what temperature does the sand have to be heated to, and for how long?

Editor: What an interesting way to store root vegetables; I've never heard of it! Readers, have you heard of this method? If so, how does it work?
