The sweet onion bruises easily and needs special handling  – so be aware – there’s more to it than leaving them in the box they came in.  If you plan to use them within a week or so, you can leave them out on the counter. For longer storage look for a place that will allow you to keep your sweets cool, dry, and separated.

One way you can do this is by wrapping each onion individually in paper towels and then place them in a brown paper bag in the refrigerator. This is storage method will keep them, for up to a month.
