How to Make Black Garlic: A Step-by-Step Guide

Black garlic is a flavorful and health-boosting delicacy that’s made by fermenting whole bulbs of garlic over several weeks. The result is a sweet, tangy, and umami-packed garlic with a soft texture, often described as “black gold.” Not only does black garlic taste amazing, but it also enhances garlic’s health benefits, offering powerful antioxidants and immune-boosting properties. The process to make black garlic at home requires patience but is straightforward. Here’s how to do it.

What You’ll Need:

  • Whole garlic bulbs (as many as you want to ferment)

  • A rice cooker, slow cooker, or fermentation box

  • Aluminum foil (optional)

  • Patience (it takes about 2-4 weeks)

Step-by-Step Guide to Making Black Garlic:

1. Choose Fresh Garlic Bulbs

  • Start with fresh, healthy garlic bulbs. Make sure they are firm and free of any mold or bruises. Organic garlic is a great option if you want to ensure no chemicals are involved in the process.

2. Prepare the Garlic for Fermentation

  • No need to peel the garlic—you’ll leave the skin on the bulbs during the entire process. Some people choose to wrap each garlic bulb in aluminum foil to help retain moisture during the fermentation process, though this is optional. If you prefer, simply place the bulbs directly into your cooker.

3. Set Up Your Cooker

  • Rice Cooker Method: Set your rice cooker to “keep warm.” You do not want to use the “cook” setting, as it will overheat and cook the garlic, not ferment it. The garlic needs to be held at a low, consistent temperature (around 140°F-170°F or 60°C-80°C).

  • Slow Cooker Method: If you are using a slow cooker, place the garlic bulbs inside, set it to the lowest possible setting (usually “keep warm”), and keep the lid on throughout the process.

4. Let the Garlic Ferment

  • Leave the garlic bulbs in the rice cooker or slow cooker for 2 to 4 weeks. The temperature should remain stable throughout this time. Check every few days to ensure the cooker is still running at a consistent temperature.

  • You’ll notice the garlic gradually turning darker and softer, and it will start to develop a sweet, caramelized aroma.

5. Check the Garlic

  • After about two weeks, check the garlic to see if it has turned black and soft. If it’s not fully black or still has a firm texture, leave it for another week or two. The longer you ferment the garlic, the richer the flavor will become.

6. Store the Black Garlic

  • Once the garlic has fully turned black, remove it from the cooker and let it cool. Peel off the outer skin to reveal the dark, soft cloves inside.

  • Store black garlic in an airtight container in the refrigerator for up to three months. You can also freeze black garlic for longer storage.

Benefits of Black Garlic:

  • Rich in Antioxidants: Black garlic contains higher levels of antioxidants than fresh garlic, which help protect the body against free radicals and oxidative stress.

  • Boosts Immunity: Like fresh garlic, black garlic is known to support immune function and help ward off infections, but with enhanced properties due to the fermentation process.

  • Supports Heart Health: Black garlic has been shown to help lower cholesterol levels and improve circulation, promoting better cardiovascular health.

  • Aids in Digestion: Black garlic is easier to digest than raw garlic, making it a good option for people with sensitive stomachs.

  • Improves Flavor: The fermentation process brings out a sweet, tangy, and umami flavor, making black garlic a gourmet ingredient in sauces, marinades, and even desserts.

How to Use Black Garlic:

  • Spread on Toast: Mash black garlic into a paste and spread it over toast or crackers for a savory snack.

  • Add to Sauces or Marinades: Use black garlic in salad dressings, sauces, or marinades to add depth and complexity to your dishes.

  • Blend in Smoothies: If you’re adventurous, add a clove of black garlic to your smoothies for a unique twist with health benefits.

  • Toppings for Pizza or Pasta: Sprinkle chopped black garlic over pizza, pasta, or salads for a flavorful garnish.

  • In Soups or Stews: Add black garlic to soups, stews, or broths to enhance the umami flavor.
