My onions came up so nice and healthy this year. Even the sets I bought on clearance from Dillons after they had sprouted in their bag came up nicely in the wet weather we had this spring. But then, a hot spell hit and some of my onions got confused and started flowering, called bolting.
Once an onion starts flowering, there’s no way to stop it. Unfortunately, the flowering process slowly destroys the onion since the plant is sucking the nutrients out of the onion in order to feed the seed-producing flower.
All is not lost, however. Bolting onions can be chopped up and dehydrated just like other onions. It is a relatively simple process if you have a home dehydrator, which I highly recommend for anyone serious about food storage.
First, gather all your bolting onions and wash them thoroughly.
Chop them into small bits. (It may help to use goggles during this part of the process to minimize watery eyes.) It’s okay to chop up the flowering sprout, though I threw the flower itself into the compost bin.
Spread the chopped onions on the trays of your dehydrator, adding a screen if necessary to keep them from falling through the cracks.
Dehydrate at 130 degrees for about 7 hours or until thoroughly dry. Use the dried onions as you would use minced onions, such as in soups or casseroles.
