Add the peeled garlic cloves to a clean 16-ounce (475 ml) wide-mouth mason jar, filling the jar no more than about three-quarters full.
1 to 1¼ cups (~ 4½-5 oz / 128-142 g) peeled whole garlic cloves
Pour the raw, unfiltered honey over the garlic until the cloves are fully submerged. Use a chopstick, skewer, or butter knife to gently stir and release any trapped air bubbles, allowing the honey to settle completely around the garlic.
1 cup (12 oz / 340 g) raw, unfiltered honey
Add additional honey as needed to keep all cloves covered, leaving about ½ inch (1.25 cm) of headspace at the top of the jar to allow for fermentation activity.
Seal the jar with a loose-fitting lid or fermentation lid. Do not tighten the lid fully.
Place the jar at room temperature, out of direct sunlight, and allow it to ferment for 3 to 4 weeks. During the first 7 days, gently turn the jar upside down once daily to coat any floating garlic with honey. Briefly loosen the lid each day to release built-up gas, then reseal loosely.
As the garlic ferments, bubbles may form, the honey will thin, and the cloves may float. These changes are normal.
Begin tasting after 2 weeks. For a mild, sweet garlic flavor, use earlier. For a deeper, more mellow flavor, continue fermenting for 3 to 4 weeks or longer.
Once the desired flavor is reached, tighten the lid and store the jar at room temperature or refrigerate after opening for longer-term stability.
