I've had cases of canning jars for over 10 years that have sat there... and sat there... and sat there... These have now become my very favorite storage system for my kitchen pantry, in the whole wide world!
I keep powders, salt, grains, rice, beans, sprouting seeds, dehydrated veges & fruits, & tons of other stuff in them. I use both quart and pint size.
Since they're glass, they won't absorb flavor or odor. They're see through, which makes for easy locating - And they're pretty!!!
They're the same size, & the wide mouth, especially, are stackable (either size could be stacked in 2's, but no more... for safety purposes, of course)
The size of the openings makes them pourable AND scoopable, and best of all... THEY'RE CHEAP!
I'm so addicted now. I went to Walmart & purchased a ton of white plastic jar lids. Cause they're one piece, and they're pretty too! They were on sale a couple weeks ago for $1.50 a box. I think there are 8 lids per box.
Try it. You'll love it!
