Black Garlic: The Mysterious and Flavorful Ingredient That’s Taking Over the Culinary World

Black Garlic: The Mysterious and Flavorful Ingredient That’s Taking Over the Culinary World

Black garlic looks like regular garlic, except it is inky black. Plus, black garlic is made, not born: Anyone can “cure” regular ol’ bulbs of garlic in a slow cooker (for three WEEKS!) to get heads of garlic to transform into tender, mild, balsamic-like, tarry black garlic to eat by itself or add to recipes!

The black garlic flavor is just as unique as its appearance. If this distinctive ingredient piques your interest, everything you need to know about making and using black garlic is here!

What is black garlic?

Black garlic is a product of aging or “curing” regular garlic. Garlic bulbs are heated on very low for weeks to produce black garlic. You can buy it online or in stores, or you can even make your own. See our recipe below!

What does black garlic taste like?

Black garlic has a more mild garlic flavor than regular roasted garlic. The flavor profile can be described as sweet and syrupy with a hint of tamarind or balsamic vinegar. 

The flavor of black garlic also depends on the fresh garlic that was used to make it. If the fresh garlic has low sugar content, black garlic will have an acidic flavor, resembling tomato paste. On the other hand, fresh garlic with high sugar content will produce a mild and sweet, caramel-like flavor.

How to make black garlic

Making black garlic is an easy but lengthy process. Here’s how to do it!

  1. Using the coarse side of a new, dry sponge, scrub garlic bulbs and remove any dirt. Do not peel the bulb or separate the cloves. Also, avoid washing the bulbs with water.
  2. Set a slow cooker on the warm setting (low isn’t low enough, so make sure it’s on warm). 
  3. Place the bulbs inside the cooker. Make sure you leave some space between the bulbs. The bulbs should not touch each other as they are heated.
  4. Maintain temperature between 140F to 190F to age the bulbs without cooking them.
  5. Cover the slow cooker and allow the bulbs to rest in the heat until they turn black and tender. This should take around three weeks.
  6. Check the slow cooker regularly to make sure it is set on warm, not low-temperature settings. It will turn hard at first, but will soften as your curing process approaches three weeks.
  7. Once ready, remove from the cooker to cool. Store fully cooled bulbs in an airtight container and move to the refrigerator.

How to tell when black garlic is done

When making black garlic in a slow cooker, it can be hard to tell when black garlic is ready. The bulbs will turn black and hard after about two weeks. However, it’s still too early to remove them from heat. Wait until the cloves begin to shrivel a bit. Once that happens, use your finger to see if the bulbs are tender. If the bulbs are soft and spongy, your black garlic is ready!

Don’t want to wait to cook black garlic yourself? Here are whole heads of black garlic from Amazon. Here are peeled cloves of black garlic, too.

How to store black garlic

Storing black garlic is simple. We recommend keeping opened containers of black garlic in the refrigerator, though some keep theirs in an airtight container away from heat and light.

When stored properly, you can continue using black garlic for up to three months.
