When it comes to storing food, glass is preferable to plastic. I have found quart size canning jars to be useful for storing many things.
While they can certainly be used for dry goods, here’s an example of how I use them for liquids.
The picture above shows four jars in my refrigerator. The first has broth and onions left from a pork roast I cooked in the crock pot. I almost always pour broth or stock into these jars.
The second is a jar of sun tea. I place four tea bags in a quart of water and leave it in the sun for several hours. I then dilute it with an equal amount of water.
The third is a jar of mint infused water. When making mint tea I remove the leaves from the stem, but when making an infusion I just put stem and leaves in the water. It’s much quicker, but the mint flavor is more subtle. I used this jar of mint water to dilute the sun tea.
The last jar is either cucumber basil water (yum!) with the cucumbers and basil already removed or it is hummingbird nectar. I can’t remember which and both are clear.
