Think about it, when you're canning, you're essentially creating a mini-ecosystem in a jar, and you want to make sure that ecosystem is healthy and happy. Boiling lids helps to achieve just that, by killing off any unwanted microorganisms that might be lurking around. It's like giving your cans a spa day, if you will!
Now, you might be wondering, how do I boil these lids, anyway? Fear not, dear reader, it's easier than you think! Simply place the lids in a pot of water, bring it to a rolling boil, and let them simmer for a few minutes. Voilà, you've got yourself some sterile lids ready to rock!
