... chewy onion
there is a known-since-dark-ages method for harvesting onions - they have to dry in the field for best storage life. with the current just-in-time and insta-everything trend, the established method appears to have been tossed.
I have noticed it's getting worse by the year. early in the season thru mid season - rubbery/gummy outer layers, especially at the top. 2-3 layers past any dry skin that may still be on the onion. later in the season as much as 50% of a 3 lb bag of onions will be rotting in the middle. I suspect they are not drying the onions enough prior to storage and/or not storing them at a good temp/humidity.
sometime about Feb I stop buying onions at Giant and buy them at Weiss - different packager at Weiss and so far I have decent luck avoiding the rotting onions at Weiss.
fwiw, btw, fyi, and all that.
