Blanch the garlic: Bring a pot of water to a boil. Blanch the peeled garlic cloves for 30 seconds to remove the raw edge. Drain and let them cool completely.
Pat dry the garlic: Use clean paper towels to pat the garlic cloves dry. It’s important to do this step well—wet garlic is more likely to turn blue or green after pickling.
Prepare the brine: In a small saucepan, combine distilled white vinegar, water, soy sauce, sugar, honey, sesame oil, ginger slices, and optional spices like red pepper flakes and Sichuan peppercorns.
Bring the mixture to a simmer over medium heat for 6 minutes, stirring until the sugar and honey dissolve. Remove from heat.
Pack the garlic: Place the cooled garlic cloves into a sterilized glass jar. Pour the hot brine over the garlic, making sure the cloves are completely submerged.
Cool: Let the jar cool to room temperature (about 1-2 hours) before sealing it tightly.
Storage: Store the jar in the refrigerator for at least 5 days before eating to allow the flavors to develop. The pickled garlic will keep for 2-3 months in the fridge.
Notes
Ingredient selections:
Garlic buying tips: Buy fresh, firm garlic cloves that are bright and free of soft spots and no visible sprouts.. Avoid wet or soggy garlic.
Sichuan peppercorns: Use whole, red-colored peppercorns in vibrant dark red. Avoid black and brown ones that look dry and moldy.
Storage Tips
Always use a clean, non-reactive utensil (e.g., stainless steel, plastic, or wood) to remove garlic from the jar to avoid contamination.
Ensure the garlic cloves are fully submerged in the brine to maintain freshness and prevent mold or spoilage.
Let it Cool First: After pouring the hot brine over the garlic, allow the jar to cool to room temperature. This typically takes 1 to 2 hours, depending on the environment. This step prevents rapid temperature changes that could crack the glass jar and also stabilizes the pickling process.
Store in the refrigerator: Once the jar has cooled completely, place it in the refrigerator to stop any microbial activity and ensure food safety.
Refrigerated Shelf Life: Pickled garlic stored in the refrigerator can last up to 2 to 3 months, thanks to the high acidity of the vinegar acting as a preservative.
Flavor Development: For the best flavor, let the garlic sit in the brine for at least 5 days, though 2 to 3 weeks is even better for deeper flavor infusion.
Why Garlic Turns Blue/Green
Natural Enzymatic Reaction: Fresh garlic contains sulfur compounds and natural enzymes. When exposed to acidic environments like vinegar, these compounds can react to form pigments, resulting in blue or green hues.
Type of Garlic: Younger or fresher garlic, especially if it’s not fully cured, is more prone to turning blue/green due to higher enzyme activity.
Minerals in Water or Utensils: Trace minerals like copper or iron in water or reactive utensils (e.g., copper or aluminum) can trigger discoloration.
Is It Safe to Eat?
Yes! The blue/green color is purely aesthetic and does not affect the safety or taste of the garlic. It’s perfectly fine to eat pickled garlic with this discoloration.
How to Prevent Blue/Green Garlic
Use Mature Garlic: Choose garlic that’s well-cured and firm, avoiding younger, "wet" garlic for pickling.
Blanch the Garlic: Blanching garlic cloves for 30 seconds helps deactivate the enzymes responsible for color changes.
Use Distilled Water and Vinegar: Opt for distilled water and vinegar to minimize mineral content that can contribute to discoloration.
Avoid Reactive Utensils: Use glass jars and non-reactive utensils (e.g., stainless steel or plastic) instead of copper or aluminum during preparation and storage.
