The Texas 1015Y sweet onions are in stores now and I wondered if they
could be frozen for later use. Found a University of Nebraska site that
said yes and here's how to do it.

Today I chopped in the food processor, two large 1015Y onions that
weighed right at four pounds for the two. Biggest darned onions I ever
saw, almost bought a whole sack of them but had no place to store them.

The process is to peel the onions, cut off top and root ends, cut into
one-inch squares and then put no more than two cups into the food
processor at a time. I then pulsed the onions about three times,
chopping them into recognizable pieces. Once chopped I took the chopped
onions out of the processor and spread them onto a large bun sheet. Once
I had a layer about a half inch thick over the whole sheet I covered
them with plastic wrap and then stuck them in the freezer. They will be
in there for two hours and about an hour of that has gone by already.
Once frozen I will cut them into one-cup squares, insert into a vacuum
bag, and then seal and put back into the freezer. Theory is that the
onions will not degrade or lose flavor this way. I will post back after
I open one of the bags a few days down the road.

If it works well I will probably go ahead and buy enough to put up about
twenty cups of chopped onion, that should be enough to last us a year
and I do love those sweet onions.
