Prepare a boiling water bath canner and 10 half pint jars. Wash new lids and rings in warm, soapy water and set aside.
Combine the apples, cranberries, sugar, water, and lemon juice and zest in a 8 quart (or larger) nonreactive pot over high heat. Bring to a boil, stirring regularly. Reduce the heat to medium-high and cook for 20-25 minutes, until the cranberries pop and the apples soften.
At this point, start watching closely for signs that the jam is beginning to thicken. Because both apples and cranberries are naturally high in pectin, you won't need any additional pectin to help this jam set, as long as you cook it until thick and begins to cling to the walls of the pot. Keep in mind that it will thicken as it cools.
Remove the jam from the stove. Use canning tongs to remove a hot jar from your prepared canner. Funnel the hot compote into the jar, leaving 1/2 inch headspace. Remove the air bubbles.
Wipe the rim, apply a clean, new lid and a ring and return the jar to the canner. Repeat this process with the remaining jars and jam. Process the sauce for 10 minutes, adjusting for altitude if you live above 1,000 feet in elevation.
When the processing time is up, turn off the heat, remove the lid from the pot and let the jars stand in the pot for an additional five minutes (this allows them to cool more gradually, which helps prevent siphoning and should also help develop a more robust seal).
Remove the jars from the canner and set them on a folded kitchen towel. Let them sit undisturbed for 12-24 hours so they can fully cool and seal. Before storing, make sure to check that the seals are firm and unbending. Sealed jars are shelf stable up to 18 months, any unsealed jars should be refrigerated and used promptly.
I made this jam without the addition of cinnamon, nutmeg, ginger, cloves, cardamom or allspice. However, I know that the addition of one or two of those spices would be quite nice. Feel free to explore and customize the spices to suit your tastes.
