Today marks the start of a contest for a set of gifts from Fillmore Container: a dozen straight-sided, slightly tapered, unembossed half-pint jelly jars; a dozen one-piece caps in the winner’s choice of color; and a copy of The Joy of Jams, Jellies, and Other Sweet Preserves, my guide to making all kinds of traditional sweet preserves in traditional ways, without added pectin.
The canning jars are just like half-pint Ball and Kerr jars except that there are no lumpy parts to avoid when affixing a label. Unlike Ball and Kerr jars, these jars come in a box with top flaps, which you can fold down to protect your preserves from dust and light when you store and transport them.
The caps come in three colors: gold, silver, and white (black ones aren’t currently available but will be later this year). The raised center of each cap makes the vacuum seal easy to see. The sealing ring is white, as is the rest of the cap’s underside. Called Plastisol, the sealing compound is appropriate for both boiling-water canning and pressure-canning. The lids should be briefly soaked in hot water to soften the Plastisol before they are screwed on to the jars.
Because people who don’t do their own canning are often flummoxed by flat jar lids, one-piece caps are nice to have when you’re planning to sell your preserves or give them to friends or relatives. And I’m especially pleased that I can place a 2 ½-inch round label on top of one of these caps without some of the type ending up covered by a ring.
Only U.S. residents are eligible for this contest. To enter, simply append a comment to this post by June 3. A winner will be chosen at random the next day.
By the way, you can probably tell from the top photo that it’s rhubarb season in my garden. The recipes for Rhubarb-Rose Jam and Strawberry-Rhubarb Jam are from The Joy of Jams, except that for this batch of Rhubarb-Rose I increased the quantity of rose petals (from pink-flowered rugosas) to 4 ounces, with a beautifully colorful result. For another idea about what to do with all that rhubarb, see my recipe for Blueberry-Rhubarb Jam, in my guest blog post on the Fillmore Container site.
