Last week we showed you our grain and pasta collection, stored in vintage Ball jars. We still need lids for these vintage jars to seal our grains airtight against moths and other pantry pests. As it turns out, though, the usual metal ring and lid combo may not be adequate for storage. Read why below.

The ring and cap method of sealing these jars is not necessarily airtight on its own. That method was designed for the canning process. During that process the air is sucked out of the jar and the rubber-lined lid is sealed, airtight, against the lip of the jar. The ring is just there to hold it in place during that process.

These rings and lids won’t necessarily keep your jars airtight on their own. For that, it’s better to use these (admittedly less cute) plastic sealing lids. You can get them in hardware stores and on
