Lightly break the skins by pricking with a toothpick or knife, gently crushing with a potato masher, or giving them a couple of pulses in a food processor. I prep a few pricks with a toothpick so that the cranberries remain mostly whole.
Place cranberries in a clean jar. Slowly pour the honey over the berries, allowing the honey seep through each berry. As the honey settles, add more honey to ensure the cranberries are covered.
Tighten the lid (lined with parchment paper if the lid is metal) and gently turn the jar over a couple of times to coat all the cranberries with the honey.
Set the jar upright on a small plate and loosen the so gas can escape as fermentation builds pressure.
Leave the jar at room temperature, out of direct sunlight, for 1-2 weeks. Once a day, tighten the lid, gently turn the jar to recoat the cranberries, then set the jar upright and loosen the lid again.
Start tasting after one week with a clean spoon, then every day or two until you like the flavor. I prefer mine at about 1½ weeks.
Enjoy!
