Keep Food Longer In Glass Jars
I’m trying to figure out how to keep food fresh longer. I applied some new tips for storing fridge ingredients and produce, and it worked so well that I started learning more. I discovered pantry items spoil sooner in their original packaging—but stay fresh longer when stored in glass jars. For example, nuts can stay fresh for 18 months in a glass jar, whereas in the original packaging they last only about 6 months. Brown sugar won’t harden either, because a glass jar with a canning-style metal lid creates an airtight seal. I also transferred rice cereal and marshmallows into glass jars, which looks amazing! Most spices can stay fresh for up to three years.
Before I learned this, I had a large plastic jar of ground black pepper from Costco. After opening it, the lid didn’t close properly; the pepper didn’t go bad, but it lost much of its flavor. Recently, I transferred a new jar of black pepper into a glass jar with an airtight lid. Now, I only refill the everyday shaker from it.
Beautiful Look of Real Food
Both of my boys will move out by the end of summer, so I really need to keep food fresh longer since there will be fewer eaters.
Another benefit of glass jars is that they take up less space than the original paper or plastic packaging. I was pleasantly surprised—by using tall half-gallon jars, I’m utilizing vertical space, which helps with bulky items like sugar and flour and saves a lot of shelf space. And I really like how it looks! The brightly colored original packaging creates visual clutter, whereas the uniform glass jars look like wholesome, healthy food—not like screaming packaging from a store shelf.
