In all honesty, it tasted like a nearly indistinguishable substitute for demi-glace, and I immediately thought of French Onion Soup. If one needed a vegetarian version, this reduction, cut with a splash of vegetable stock, stock could replace beef stock and no one would miss a beat. I let mine reduce a bit more, to about a quarter of its original volume, and now I had a luscious, syrupy reduction that I honestly could drink a glass of: pure, sweet, black garlic heaven.
Chicken Breasts: I attempted a black garlic brine for one of the chicken breasts using a quart of water, ¼ cup of salt, 5 cloves of black garlic, 1 thai chile, and a few pieces of lime peel; after brining it overnight, I seasoned, seared and roasted it. I wanted the preparation after the brine to be as simple as possible so that I could really judge how much the black garlic flavor transferred to the breast.
In truth, there was not much infusion in the meat; while it was tender and juicy from the brine, it tasted like little more than chicken. Interestingly enough, I did notice that some of the drippings that had fallen as the breast roasted had caramelized on the roasting plan. I dipped my finger in them and tasted, and the favor explosion in my mouth caught me by surprise. Its concentration and richness were like that of the wine reduction, but this time the profile was much more savory, as it had now been combined with the flavors of well-seasoned chicken instead of sugar-rich wine. The caramel-colored goo tasted of umami, its flavors and texture akin to a rich, slightly sweet soy sauce.
Lessons Learned: I was starting to get a sense of how to cook with the black garlic, from both my misses and successes. It made sense that a very gentle method of developing its flavor wasn’t going to do much; after all, the garlic had already been through a very gentle and mellowed fermentation process to get to its current state. To unlock something even deeper, it was going to take more intense cooking: techniques that involved direct heat might be the key to getting something entirely new out of what is already quite the unique ingredient.
Infusing butter, brining, and braising didn’t quite work, perhaps because these are slow cooking methods deigned to gently coax the flavors out of ingredients. Roasting, on the other hand, applies direct, dry heat; harsher than a liquid simmer, that worked out much better, even in just a few drops of drippings. Reducing almost all of the water out of the black garlic and wine yielded similar, outstanding results.
Chicken Legs, Part 2: With this in mind, I rubbed the other chicken leg all over with a paste I’m calling a “Korean Jerk,” made from a tablespoon of neutral oil, a tablespoon of black garlic paste, salt, pepper, and a ¼ of a finely minced habanero (roughly a teaspoon or less), then I wrapped it tightly in plastic wrap and put it in the fridge to marinate overnight. The rub was a bit challenging to stick, so you could probably add a bit of corn starch if you wanted, but if you spend a minute really rubbing it in, that and the time marinating in the fridge will do just fine.
The next day I pulled the leg out and noticed the stunning change in color that it had picked up while marinating: it was now amber all over the skin, with tiny flecks of bright orange from the habanero and sexy splashes of deep black sheen from the paste. I hit it with a touch more salt and pepper and set it to roast at 350 for about 20 minutes, finishing at 450 with a drizzle of olive oil to help crisp up the skin a bit. This result was the best by far. The black garlic provided a nice, soft background for the heat of the habanero, just as you notice in traditional jerk seasoning, and it quite naturally went great with the chicken. All in all, the flavors were infused, balanced, and tasty.
In retrospect, I probably could have seared it if I wanted to really test my theories of intense heat and get a crispier skin, but I was worried about the black garlic burning. I guess we won’t know until you try it. So try it!
Next up were the thighs; these I was really excited about: I deboned them completely and stuffed them with a handful of cloves of black garlic and some very thin slices of lemon, rolled them up, tied them, and seared them on all sides. Then I whisked about a quarter cup of the black garlic paste into a cup of particularly earthy cocoa & coffee barbecue sauce I’d made the week prior. I placed the thighs back into the pan in which I’d seared them, added the black garlic barbecue sauce, finished with stock until the thighs were mostly submerged, then braised it, covered, at 350 for about 15 minutes.
This was another big success. The high concentration of the paste and the thick, rich sauce as a vehicle to carry its flavor meant that everything really came together; it was reminiscent of a red mole sauce, sweet and earthy as it clung to the chicken thighs. Moreover, inside the rolled thighs was another completely different flavor combination of bright lemon, sweet, rich black garlic, and savory dark meat, all keeping one another in check and adding even more overall depth to the dish. A bite containing a bit of everything together was almost indescribable: you got bright, tart, sweet, earthy, salty, tangy, and more, all hitting you at once. It was the veritable surprise party in your mouth that comes only from multiple layers of flavors and ingredients brought together with care.
On the side I made a simple green salad and dressed it with a black garlic vinaigrette, emulsified in the blender (hyperlink to emulsified vinaigrettes article) and containing 5 cloves of black garlic, about 3 tablespoons of red wine vinegar, some salt and pepper, and a slow stream of neutral oil (I used neutral as opposed to olive oil in order to let as much black garlic flavor come through as possible). The vinaigrette was subtle and pleasant, the black garlic adding a sweetness that was richer and more complex than if I had simply used white sugar.
I did notice that, even in the blender, there were still small bits of black garlic that did not blend into the dressing. This was not an issue because the little morsels were delicious, but it was worth noting the continued resistance to easily break down and emulsify. That being said, I think these tiny flavor bursts in the salad were as much a flavor ‘pro’ as they were a consistency ‘con,’ but if you’re not into it, you can always strain them out.
All the stock I used throughout the cooking process was a black garlic chicken stock I made by rubbing the chicken carcass, thighbones, and wing tips with black garlic paste before roasting them at 375 for an hour and a half; I also added a handful of cloves to the stock as it simmered. The color was absolutely gorgeous, sort of a chestnut brown; and the aroma that filled my entire house was like the combination of a magical forest and a dark chocolate sauna. It was nutty and sweet and savory and gamey, and it brought me several times to stand over the pot, inhaling deeply and smiling as its heavenly, honey perfume wafted about my head.
Unfortunately it tasted far more like chicken and stock scraps than it did like black garlic, even after it reduced for several hours; it was perplexing to get so much by smelling and so little by tasting, but I have had the same experiences with certain wines. Whether it’s me or what I’m smelling, I think I can pick up more complexity from aroma than I can from taste. It also may have to do with my previously noted observations of gentle versus harsher cooking with this particular ingredient: simmering stock is definitely on the gentler side, and there’s a lot of water, scraps, and bones to dilute the black garlic’s flavor.
I froze most of the stock, reserving just under a quart to keep on hand for one last use. I ended up using it to make farro the next day, and as the hearty grains of farro took their time soaking it up, the stock reduced to literally nothing, as it goes when you cook most grains. I ran my finger across the bottom of the pan after the farro came out, and when I tasted it, the sweetness was right up front, as if I had added a spoonful of caramel to the pot at some point. The hearty flavor and toothsome texture of the whole grain married with this sticky sweetness, straddling the line between sweet and savory, kind of the way a muffin sometimes does.
From this point I could have added dried fruit and nuts or fresh herbs and feta and either would been perfect. I went with a squeeze of lemon and some thinly sliced kale, then topped it with chunks of butternut squash that had been roasted in some of the leftover black garlic barbecue sauce, then tossed with a little mascarpone cheese.
There are literally thousands of other directions you could go with black garlic. Its flavors are very complementary and it’s hard to overdo it, which is most definitely not the case with raw garlic, as I’m sure you know. Plus it happens to be rich in antioxidants (twice the content of raw garlic) and cancer-fighting agents. Bonus!
Try marinating some Korean style short ribs (or almost any protein) overnight in a black garlic marinade to get the most out of its flavor. Better yet, go uber-simple and serve a pile of whole cloves on a cheese plate to really blow people’s minds. You can put time and love into taking its flavor to the next level, or let let the black garlic speak for its delicious self: both will be crowd pleasers. I’m glad I finally got to know this delicious and unique ingredient. It’s time you did the same!
THE ORIGIN OF BLACK GARLIC
It’s one of those things that you’d guess has been around for thousands of years, fermenting in crocks. But it’s quite new, created with a high-heat fermentation process that turns regular garlic into black garlic in 30 days. While it probably developed within the last 10 years in Korea, the American product was invented by a Korean-American named Scott Kim in Southern California, who has a patent pending on the process. He is currently the only supplier in the U.S.
