I've always been on top of managing my spices, but I wasn't satisfied with my assortment of containers. They were hard to clean. They were plastic. I couldn't find replacements. It was awful (or slightly annoying, depending on how excited you get about these types of things).
When we moved, I saw a perfect opportunity to transfer our spices to small jam jars. Jade, a high school friend, implemented this method a couple of years ago, and I've been planning to replicate it ever since.
I bought my jars at Canadian Tire. I have a lot of spices, so I bought 3 boxes of 12. I also bought some cute lids to mix it up. The total cost was about $30.
There are many benefits to this system, beyond the low cost: the jars are glass; I can clean them easily; I can label the lids with a permanent marker and it won't come off in the dishwasher; I can find replacements easily; and, since the jars can be stacked, I can spot the spices I need (most of the time).
I have nothing but good things to say about these jars!
