This sweet-tart jam recipe is summer flavor divinity but combined with the two different ways of processing the lemons AND the steam canner saving so much time in the canning time, this tutorial will be on your regular rotation in no time.

Cranberry Lemon jam calls for
3 pounds Meyer lemons, washed well
1 bag or 1 ½ cup cranberries (okay if frozen from Thanksgiving time)
1 ½ cup sugar
Simmer WHOLE Meyer lemons in a large saucepan of water for about 20 minutes or until a fork slides into them easily.
Cool lemons until you can handle them easily, either by resting on a cutting board (slow) or submerging in an ice bath (much faster)
While the lemons cool, add the cranberries and sugar to a smaller saucepan and turn on low to medium low. They will very slowly cook, bursting, and the sugar will dissolve. Stir occasionally.
Working over a bowl, with a knife and a grapefruit spoon or other semi pointy spoon, cut them in half, scoop out the visible seeds, and put the lemon halves into a food processor like this one
You can also use a blender to puree the lemon into a smooth mixture as well.
Or a food mill like this one-
just slice the lemons into quarters or even a bit smaller to lessen the effort required to work them up.
Once the lemons are super smooth, combine the lemon puree and the cranberry all together. Turn on medium low to bring to a simmer. You want the mixture to be hissing, bubbling, and the bubbles bursting at the surface. This should be happening in about 10 minutes.
Prepare the steam canner.
Add the water to the steam canner, assemble the jars, new lids, funnel, ladle, and turn steam canner burner on low.
Get the Steam Canning Mini Resource Guide- It’s a PDF equipment checklist + fact sheet about how to get started with steam canning!
One at a time, fill the jars with the simmering jam, leave a quarter inch headspace, apply a new lid and ring, and set on the rack of the steam canner. Repeat with remaining jars.
Put the lid on the steam canner and turn the heat up to medium high. When the dial on the steam canner indicates you are in the “zone” start the timer for 10 minutes, remembering to adjust for altitude (5 minutes of processing time added for every 1000 feet elevation). When the time is up, turn the burner off and wait till the lid of the steam canner has cooled significantly. Lift the lid away from you, and be aware that steam will come pouring out from the canner.
Lids will seal immediately or as long as 12 hours after you remove them from the canner. Label sealed lids and store.
That’s it, Wildflowers! It is delicious with cream cheese on a bagel, stirred into a sunny whiskey cocktail, or on a meat and cheese sandwich.
I have a little secret, though.
The whole process of making this jam is part of my Steam Canning Workshop video course. That’s right… you can watch me make this jam, step-by-step, in the course, along with a bunch of other recipes chosen for which time saving techniques they’d teach you- learn more here!
