Black garlic isn't a special variety of garlic; it's regular garlic that has undergone a fascinating transformation. Through a process of slow aging under controlled heat and humidity, the cloves turn a deep black colour and develop a remarkably different flavour profile.
The Magic of the Maillard Reaction
The secret behind black garlic's unique character lies in the Maillard reaction. This chemical process, also responsible for the browning of bread and the rich flavours of roasted coffee, occurs when amino acids and sugars react under high temperatures. In black garlic, this reaction mellows out the harshness of raw garlic, creating a sweet, savory, and almost balsamic-like flavour with hints of molasses, licorice, and even chocolate. The texture also changes, becoming soft and slightly sticky, reminiscent of dried fruit.
Making Black Garlic at Home
While you can find black garlic at specialty stores and online, it's surprisingly easy to make at home, it just requires some patience! Here's a simple method:
Ingredients:
- Whole bulbs of garlic
Equipment:
- Rice cooker or slow cooker
- Aluminium foil
Instructions:
- Prep the Garlic:
- Ensure your garlic is fresh, clean and free from any signs of spoilage before starting the process. If necessary, clean the garlic bulbs gently to remove any dirt or debris. You can wipe them with a damp cloth or brush them lightly.
- Keep the garlic bulbs whole and unpeeled.
- Ensure they are completely dry before starting the process.
- Set Up the Cooker: Line the bottom of your rice cooker with foil to prevent sticking. Place the garlic bulbs inside.
- Age the Garlic: Set the rice cooker to its "Keep Warm" function (or the lowest setting on a slow cooker). Ideally, you want to maintain a temperature between 60-70°C. Leave the garlic undisturbed for 3-4 weeks, checking occasionally to ensure it's not drying out.
- The Waiting Game: The garlic will gradually darken over time. It's ready when the cloves are completely black, soft, and slightly sticky.
- Store and Enjoy: Once ready, store your black garlic in an airtight container in the refrigerator for up to several months.
Important Notes:
- If you want the garlic to age more evenly, a single layer of garlic usually proves the best result. However, if you're less concerned about perfect uniformity and want to maximise the amount of black garlic you make, you can load up the cooker a bit more. Just make sure there's enough space between the bulbs for air to circulate freely. This helps maintain a consistent temperature and prevents moisture buildup.
- The aging process can create a strong garlic odour, so it's best to do this in a well-ventilated area.
- Inspect your rice cooker or slow cooker for any damage before use. Place it on a stable, heat-resistant surface in a well-ventilated area, away from flammable materials. Avoid leaving it unattended for extended periods.
- While a rice cooker or slow cooker usually does work well, it's important to note that it’s not designed for such long cooking times and doesn’t use have precise temperature controls. For optimal results and greater peace of mind, consider a dedicated black garlic fermenter. These offer precise temperature control and enhanced safety features, ideal for the long aging process.
