In a large glass jar, combine the chopped onion, minced garlic, grated ginger, grated turmeric, sliced jalapeños, black peppercorns, and rosemary. Ensure even distribution of the ingredients.
Pour the apple cider vinegar over the mixture, ensuring the ingredients are fully submerged.
Seal the jar tightly and give it a good shake to mix everything together thoroughly.
Store the jar in a cool, dark place for about 2-4 weeks. Shake the jar daily to help infuse the flavors.
After the infusion period, strain the mixture using a fine mesh strainer or cheesecloth into a bowl.
Stir in honey to taste, adjusting the sweetness to your preference.
Transfer the fire cider into a clean glass bottle or jar for storage.
