Canning lids are just one important component of preserving the food you grow on your homestead. The age-old method of canning continues to gain in popularity as more homesteaders work to become self-sufficient.
Whether you’re an experienced canner or new to the process, canning is an effective way to extend the shelf life of your favorite homegrown foods.
In this blog, we explore the art of canning and share tips and tricks for successful preservation, including:
Can you reuse canning lids? Technically, yes.
Should you reuse canning lids? That depends.
Canning enthusiasts have debated this topic for almost as long as canning has existed. While there are some who believe that lids can be safely reused with no ill effects, most food preservation experts advise against it.
There are two parts to canning lids that work together to seal your food safely inside the canning jar. First, is the metal disk that sits on top of the opening. Second, is the band that screws down over the disk.
You can reuse the bands unless they become bent, dented, or rusty. Reusing the disks is riskier if you don’t follow some basic safety precautions.
The biggest danger of reusing canning lids is they might not seal properly. Without a good seal, your food can spoil quickly. Not only does that mean all your hard work growing it was wasted, but also the time you spent following a recipe for canning it.
False seals are one of the hidden dangers of canning, whether you try to reuse lids or not. Failing to follow the recipe correctly can lead to a false seal. Overfilling or underfilling your canning jar can also cause it not to seal properly.
The good news is you can usually tell right away if a can sealed. Tap the lid with the bottom of a teaspoon. If you hear a dull sound, the lid likely didn’t seal. Canning lids that have a good seal make a high-pitched ringing sound.
If you must reuse your canning lids, follow some basic safety guidelines to increase the chances of avoiding a false seal.
Water-bath canning is the best opportunity for reusing your canning lids. The higher temperatures involved with pressure canning can break down the sealing compound, increasing the likelihood of a false seal. Water bath canning eliminates that risk by using lower temperatures during the canning process.
Canning food from your homestead garden can preserve it for later. However, it’s important to be mindful of some common mistakes that can compromise the safety and quality of your canned food.
Consider the type of canning method you’re using when figuring out how full to fill your canner. Follow these tips for the best results.
When pressure canning, aim to fill the canner with the appropriate amount of water according to the manufacturer’s instructions. Then, put canning jars filled with the food you want to preserve into the canner. Don’t forget to leave the recommended amount of head space for a tight seal.
Most pressure canners suggest starting with 2 to 3 inches of water inside the empty canner. After you add your jars, the water gets displaced about ¾ up the jar depending on its size. Make sure the necks of the jars are above the water for the best results.
If you’re using a water bath canner, you want your canning jars completely submerged. To make sure you achieve full submersion, fill your water bath canner about halfway full of water before adding your jars. If you find you’re short of water after adding your jars, you can make up the difference by adding boiling water to the canner until your jars are fully submerged.
Most experienced canners recommend eating your canned goods within a year of the date you sealed and stored them. At most, you can extend the consumption time to 2 years.
The food inside may still technically be safe to consume after 2 years, but it won’t taste as good. That’s because home canned food loses nutrient density, which affects its texture. While it’s not going to make you sick if you eat it, you probably won’t want to eat it if the flavor is “off.”
Ideally, you should only can as much food as you and your family can eat in the off-season to prevent food wastage. And, before you eat anything you’ve canned from the previous canning season, check the seal to make sure it wasn’t compromised.
Canning is popular enough that you can find canning supplies in hardware stores, specialty kitchen supply stores, online retailers, and at big-box stores like Walmart.
Regardless of where you get your canning supplies, check the jars and rings of the lids each year before reusing them. Look for knicks in the glass around the jar’s rim, and for dents, knicks, or rust on the rings.
