First, slice your batch of jalapeno peppers into rings and discard the stems. Stuff the jalapeno slices into a quart sized jar (Ball jar or Mason jar).
Next, add the vinegar, water, honey, garlic, bay leaf, salt, Mexican oregano, black peppercorns, and salt to a pot. Bring the brine mixture to a quick boil.
Give it a quick stir, then remove the brine from heat. Cool slightly.
Pour the brine into the jar over the jalapeno peppers. Secure with a lid and let come to room temperature. Refrigerate until ready to use.
