Juice and zest the orange. You should have a few tablespoons of juice and about a tablespoon of zest.
Place cranberries, orange juice, and orange zest in a food processor.
Pulse until the cranberries are crushed. You can make it smooth or chunky like a relish. I like mine chunky.
Scrape the blended cranberries into a small jar (pint size) for fermenting. Blend in the honey and place a lid on the jar.
Ferment it for 24 hours on the counter, then store in the refrigerator. If you want it less sweet, ferment it for an extra day or two. Stir it once a day. It will become less sweet the longer it ferments.
