You might not know this about me, but I get positively giddy when I discover new canning jars. The most recent line of jars to send me over the moon? The Lock Eat jars from Luigi Bormioli. They are sleek, easy to use, and have a very pleasing heft to them.
They’re the first jars designed with the understanding that they will have multiple uses in our homes. They work beautifully for all manner of boiling water bath canning, but are also perfect for portable meals. The lid detaches completely and once removed, you’re left with a smooth container that’s ideal for yogurt, grain salads, and smoothies.
They come in two different shapes, and a number of sizes. The juice jar shape is available in 8.5, 20.5, and 34 ounces, and the straight-sided jars hold 2.75, 4.25, 6.75, and 11.5 ounces. All the Lock Eat jars are made in Italy, and are safe for both the microwave (once the lid is removed) and the dishwasher.
The lid is really easy to lock into place as well. Holding the base of the jar firmly, you just push the stainless steel arm down until it slides into position.
I’ve had a small assortment of the Lock Eat jars in my kitchen for a little over a month now and have used them for leftovers, dry good storage, packed lunches and canning. So far, I like them a whole lot.
Using them for canning feels very much like processing preserves in Weck jars. Before you start making your preserve, arrange your selected jars in a canning pot (I’m using the Lagostina Martellata pasta pot here – more on that next week). Remove the rubber seals from the lids and arrange the glass lids in the pot as well. Bring to a boil. In a separate pot, simmer the rubber seals to soften.
Once your preserve is ready, remove the jars from the canner and fill them to the bottom of the solid glass band that runs around the top of the jars. This is a little more headspace than one leaves when working with mason jars, but it makes sense once you remember that the lid sits in the body of the jar and so takes up some of the header space.
Once the jars are filled, you ease the rubber seals back onto the lids, taking care to ensure that the tab is positioned so that it won’t be in the way of the latch when you go to lock the lids into place.
Then you wipe the rims and the top interior of the jars, place the lids onto the jars and carefully lock the lids into place.
(If you’re curious about the contents of these jars, check back tomorrow, when I’ll be sharing a recipe for low sugar grape jelly.)
The Lock Eat jars play nicely with regular jar lifters, provided that you take care to place the lifter on the sides of the jars, rather than get them tangled up with the lid latch. Set them into your canning pot and process as your recipe instructs.
Once the processing time is up, remove the jars from the canner and set them on a folded kitchen towel to cool. Once the jars are completely cool, you can check the integrity of your seal by carefully releasing the clamp, grasping the lids, and lifting. If the lids stay firmly in place, the jars are sealed and can be stored in the pantry. As always, any unsealed jars should be refrigerated and used promptly.
The rubber seals can be safely reused for canning as long as they remain springy and in good shape. If they seem to be losing their elasticity, you’ll want to order new ones prior to canning with them again.
Because they want to spread the word about their new jars, the folks at Luigi Bormioli are offering up five sets of Lock Eat jars for this week’s giveaway. Each of the five winners will receive an assortment of 14 food and juice Lock Eat jars, at a retail value of $125.
