My name is Erica and I am a glass jar hoarder. Though I recycle committedly, I have a hard time parting with most glass jars, especially even, cylindrical ones without shoulders, and square-sided ones, which maximize storage space. Though I am the proud owner of a cheap plastic "mayoknife", I still hate jars which fight my attempts to get every last bit out without smearing my hands.
I live in fear that current glass jar items will be switched to plastic next time I buy them. Though I don't even keep berries in glass jars (I find paper towels and Rubbermaid preserve them for over a week), I transfer cereals, coffee, beans, flours, nuts, and dried fruit to glass jars as soon as I open them, and often freeze foods in glass. I still mourn the last of the straight-sided, metal-lidded large (2qt?) mayo jars, whose bottom cracked off after decades of use in the freezer.
I confess that when shopping in Costco, I will buy items I don't really need if they are in nice jars, as long as I can figure out some way to use the contents. Recently it was Costco's "canned" peaches, which came in a 4-pack of quart mason jars with measurement markings on the side.
I prefer my homemade bean salad, but have bought the huge glass jar on several occasions.
Anything you want to get off YOUR chest?
