Black Garlic is More Treat Than Trick

October 24, 2015

Yes, those garlic cloves (1, below) are really black.

That is real garlic you're looking at, and no, it's not a specific variety nor is it good garlic gone bad

Instead, it's black garlic. Though often described as “fermented garlic,” that’s not entirely accurate. The change the garlic undergoes isn’t due to fermentation but rather the Maillard reaction. 

If you want to geek out on the non-microbial chemical and biochemical transformations that garlic undergoes when turning black, Lucky Peach is here for you; otherwise, the important takeaway is that the Maillard reaction—responsible for making "browned" foods like seared steak, dulce de leche, and perhaps our favorite, toast—is at work here, too.

(Are you thinking tasty, browned foods sound like caramelization? You’re right of course, but they are two distinct processes—caramelization doesn’t involve a reaction with amino acids like the Maillard reaction does.)

More: All of this caramelization talk making you hungry? Time for caramel cake.

Black Garlic

If you buy black garlic (try a well-stocked grocery store), it will have cooked for a month or so (that’s not a typo) in a temperature- and humidity-controlled environment. When it's finished, the cloves will be dark brown or black, and the papery husks will be slightly darker as well (3 versus 2, above). If you’re patient, you can try making it yourself at home, either in a rice cooker, slow cooker, or dehydrator.

In an unopened package, black garlic can be stored at room temperature, but once opened, our friends at Frieda’s recommend storing it in the refrigerator for up to one month. 

Black garlic has a soft, slightly chewy texture and a sweet—and unique—flavor. It’s described as tasting like all sorts of things: figs, dates, molasses, balsamic, beef bouillon, and garlic, too, of course. Whatever you think it tastes like, one thing is for sure: Black garlic is an umami bomb that you’ll want to start adding to all sorts of dishes. 

Slice it and use it to top everything from salad, pizza, and pasta to meat and fish. Use it in dips and spreads like hummus and tapenade. Purée it and use it in aioli, vinaigrettes, and marinades. Follow Amanda Hesser's lead and turn it into a savory crumble for sprinkling over roasted vegetables.

I like esoteric facts about vegetables and think ambling through a farmers market is a great way to start the day. My first cookbook, available now, is called Cooking with Scraps.

I make black garlic. While the traditional method does take a month to produce, you can buy black garlic cookers for as little as $50. These produce 2 lbs every 9 days that are perfect. They can be frozen with no ill effects to the cloves. You can blend 5 heads with 1C of water and 1/2C of olive oil to make a mixture that can be added to salad dressing and added to rice while it is cooking. While it is "cooking", it will fill your house with a sweet garlic smell that some people will not like. I love it.

There are a couple of links above that will walk you how to make black garlic in either a rice cooker, slow cooker, or dehydrator.

I tried rice cookers and they will not maintain the proper humidity levels. I also tried slow cookers but they will not maintain the proper temperature (74C) for long enough. Dehydrators dry them out.
