Fermentation VIII: Kefir Broth

I love to make soups in the winter, and have often written about the wonders of homemade broth.  I’ve never cared much for any vegetable broth that I have tasted, and I like the deep savoriness and the economy and thrift of making meat and chicken broth. But recently, more or less by accident, I did discover an alternative.   I was experimenting with my abundant supply of water kefir, and was cooking it down to make a syrupy glaze of the type that I have enjoyed making out of kombucha.  About the original idea, all I can say is please don’t try this with kefir, because the result is rather dreadful. However, having tasted the product of one pot, I turn the heat off under the other one, which had been reduced to a little more than half its original volume. I tasted, thought, added some salt, and had something that tasted savory and surprisingly like chicken broth.  Cooked with some aromatics and herbs, the resemblance would be even more striking.

I tried the same experiment with some water kefir  made with coconut sugar, thinking that the deeper color and flavor would be attractive in this context.  But to my surprise, the faint bitterness that is detectable as an undertaste in brown sugar or coconut sugar was greatly exaggerated in the finished broth, to the point that I threw it out.  So save yourself some time and trouble and use plain sugar when making kefir that you intend to cook down.

Since I remain obsessed with fermentation months after first reading the Noma Guide to Fermentation, I decided to try combining various fungi both microscopic and macroscopic in a mushroom broth.  I had a quart of broth made from boiling down 2 quarts of water kefir.  I started with butter, which made my soup vegetarian, but if you wish to use olive oil or some other vegetable oil instead it will be vegan.  Heat about 3 tablespoons of your chosen fat in a small heavy sauce pan, and sauté one large or two small cloves of garlic finely chopped and one small onion sliced thin.  Cook them over medium low heat, stirring frequently, until they are thoroughly cooked, soft, and a bit caramelized.  Put in 3 tablespoons of mushroom powder. I used dried and powdered Sullius that I had gathered, but the most commonly available powdered mushroom is porcini.  Sautée the powder for a few minutes, and add a quart of broth to your pan. Bring to a boil, and then turn the heat down to simmer.  Now stir in 2 tablespoons of white miso paste.   Taste for saltiness. You might want more miso, but taste it first. I am working on making my own miso, but a good grade of white miso from your nearest Asian market is fine.  Simmer  the soup for 15 to 20 minutes over low heat.

The final step is to smooth it out.  You can do this with a stick blender, but in my opinion there is no alternative to a Vitamix blender to turn your soup into pure velvet.  Make sure you know how to handle hot liquids in your blender without creating a sort of fluid explosion.  When the soup is completely smooth, return it to the pan, heat gently, taste for seasoning, grind in a little fresh pepper, and serve.

There is nothing quite like the process of fermentation to produce a rich, meaty savor without the use of meat. In this basic recipe, I was experimenting with fermentation as a way to make a vegan or vegetarian product highly satisfying.  But if you are not a vegan or vegetarian, there is no reason to feel limited.  You can start with bacon fat if you want to, or add chunks of leftover cooked meat, or finish it with a dash of good sherry or a swirl of cream or both. Sautéed mushrooms would be a great addition.

It interested me that despite use of miso, this soup doesn’t taste identifiably Asian. It just tastes good. If you want something that leans more Asian, you could add a piece or two of kombu to the kefir for a few minutes  as it cooks down and finish the bowls with some diagonally slivered scallions.

Wild Mushroom Experiments


No, not that kind of mushroom and not that kind of experiment. I have been reading a wonderful new book, chef Chad Hyatt’s The Mushroom Hunter’s Kitchen, and it has led to compulsive kitchen experimenting. Hyatt writes about porcini, morels, and the other “premium” mushrooms, but also about more common mushrooms that you never encounter in upscale restaurants but might find a bagful of if you’re a mushroom hunter. He suggests substitutes where appropriate and encourages a lot of experimentation. He has me adding cooked ground black trumpet mushrooms to my umami sauce, and I’m especially interested by his mushroom leathers, in one case made from the Sullius mushroom genus that I no longer harvest because I dislike the texture so much. This makes the despised  mushroom sound worthy of a place in the take-home basket.

I happen to have a lot of lobster mushrooms in the freezer, because they are beautiful and plentiful and I can never resist harvesting them when I find them, but the unfortunate truth is that to my palate they have very little flavor at all. I love hummus, and as a low-carb person I can’t eat it often, so I was interested by Hyatt’s recipe for hummus made from salted mushrooms. I don’t have any salted mushrooms at hand currently, but I certainly do have lobsters.  They were sautéed in olive oil before freezing, and I decided to thaw a bag and try a recipe based on Hyatt’s. The lobsters went in the food processor, about 2 cups of them, with 1/4 cup of tahini, the juice of two small lemons, two cloves of raw garlic, and some additional olive oil. After a few minutes of processing and adding salt to taste, the taste was good but the texture and mouth feel were not at all what I wanted.  I moved the somewhat grainy lumpy mixture out of the processor and into my Vitamix blender, added more olive oil so that the mixture would blend, and blended it on the high setting, stirring the contents down a couple of times.   The texture was now exactly what I wanted, not totally smooth like baby food but with a texture much like chickpea hummus.  Dolloped into a bowl, sprinkled with ground chipotle chilies rather than the more traditional sumac, and garnished with chopped cilantro, it made a delicious spread. I should add that Hyatt calls for less olive oil than I ended up using, although I didn’t measure precisely.  I love the taste of top quality olive oil and lobster mushrooms have little natural flavor of their own, so for me this was a natural adjustment to make.

This first very successful experiment has me reading the book with renewed interest.  It can be rather painful to read mushroom books out of season, when there is no way to go out and find the mushrooms, but most of us who hunt mushrooms have a lot of frozen or dried  mushrooms from past successful hunts, and this can help us get busy and get them out of the pantry or freezer.  Also, specialty grocery stores have much larger selections than they used to. The last time I was in Whole Foods, I counted seven varieties of fresh mushrooms.  Buying those hideously expensive little packets of dried mushrooms from the grocery store is not really an option if you want mushrooms in bulk, but you can buy bulk dried mushrooms from several sources.  I usually use Oregon Mushrooms or buy from private foragers when I want to augment my pantry supply. By the way, know your forager. Not every forager should be trusted blindly.

In short, if you like to eat mushrooms at all, I highly recommend Hyatt’s book, whether or not you are a mushroom hunter. His creativity is wonderful.   For example, there is an entire chapter of mushroom desserts.  This is not a category of possibilities that I ever gave the faintest thought to, but the recipes look really good and seem designed to get cooks thinking. And this, to me, is the hallmark of a really successful cookbook. A good cookbook may give me a few recipes that I use verbatim, but it’s more important that it gets me excited about the endless vagaries of food and leaves me feeling that there are more possibilities than I’ve considered. Lifting simple nourishment and avoidance of starvation to an art form is what cooks do, and a good cookbook can get us very jazzed about doing it.

Keep in mind that the book has some very useful notes about lesser-known edibles but is a cookbook, not a foraging book. You will still need a field guide (and some good teachers) if you’re new to the sport.

Hyatt is selling his book directly, in both hard copy and ebook format, at the link above. As always, I don’t accept review copies. Books that I review are bought at the price that you will pay. This one is worth every penny.

Fermentation VI: Lacto-fermentation

I can’t say enough about how The Noma Guide to Fermentation is livening up my kitchen experiments, but I was fairly sure that I wouldn’t care much for ordinary lacto-fermentation. All fermented pickles and sauerkraut are made by this method, and with the exception of kimchi I’ve never really taken to any of them. But then I bought a couple of pounds of organic cremini mushrooms because they were on sale cheap and I’m a sucker for a bargain, and had to figure out something to do with them. I tried slicing them, tossing with 4% of their weight in salt, and packing into quart mason jars under pickle weights. I set them aside loosely covered, and when I next paid attention to them a week later the mushrooms had shrunk down by half and the jars were filled with fluid. I sniffed the contents, and was surprised at the strong mushroom aroma. I tasted the fluid and it was salty and had a full mushroom flavor. So I started to experiment.

This soup also contains other recent and past experiments.  If there is one thing that I want readers of my blog to do, it is play with their food. Taste, and if the tastes go well together, it doesn’t matter  whether you ever saw a recipe quite like it before.  The flavor of mushrooms and black garlic seem made for each other, and I wanted to try the combination out. I put about a cup of dried porcini slices in hot water to soak. While they soaked, I started the cooking with two cloves of fresh garlic finely minced and eight peeled cloves of black garlic chopped very coarsely. I melted a couple of tablespoons of butter in a saucepan, and added the two garlic types and three slices of bacon sliced 1/4” wide. I sautéed these ingredients slowly over medium heat until the fresh garlic was cooked but not yet coloring, and added a quart of very good chicken broth, the soaked porcinis and their strained soaking water, half a cup of the fermented creminis and their fluid, and a tablespoon of dry sherry and two teaspoons of Red Boat fish sauce. This mixture was brought to a slow boil, and turned down to a simmer for 20 minutes. Meanwhile I peeled another eight cloves of black garlic and pounded them to a smooth paste with a good pinch of salt. When smooth, I pounded in a tablespoon of fermented mushroom liquid, a tablespoon of boiled-down kombucha,  and a tablespoon of red wine vinegar. When the soup was served, a good dollop of this paste was put in each bowl, to be stirred in by the diner. Of course you could just add it to the soup in the pot, but the pleasure of smelling the rich, complex fragrance as the paste melts into the soup would then be lost to all but the cook.

Be aware that lacto-fermentation only preserves food up to a point. After a week fermenting on the counter, the cremini juice is at peak flavor in my opinion. If left at room temp it may go on to develop musty off-flavors. In my kitchen, at the one-week point it goes in the fridge.

I always use quart wide-mouth mason jars for lacto-fermenting. There are wonderful crocks made especially for the purpose, but I don’t want that much of any one product, so I stick with my jars. Good pickle weights will simplify your lacto-fermenting and help prevent mold. Good weights are glass, solid and heavy, smooth on the bottom, and have a handle on top so that you can get hold of them. Cheaper weights are often hollow on the bottom, creating an airspace that invites mold, and aren’t heavy enough to keep the fermenting veggies submerged. Good ones can be bought here or from other sources. I have one hand-thrown stoneware pickle weight that I love, and have also used smooth rounded rocks of the right size after putting them through the dishwasher. This last is unscientific and probably unsanitary but I bet our ancestors did it too.

 

Fermentation II: Black Garlic and other goodies

 

 

Yesterday’s post was about a truly remarkable cookbook, The Noma Guide to Fermentation. Today I’ll talk about a kind of high-temperature enzymatic reaction, the making of black garlic and other blackened goodies. Properly speaking this is a Maillard reaction and not a fermentation, but let’s not quibble when the result is so delicious.

These products need to be made at a temperature of 140-150 degrees. This is hard to achieve without a specially built chamber, although I notice with interest that a household appliance built especially to make black garlic is available on Amazon. A rice cooker on “keep warm” is suggested, but mine turns off automatically. I am trying my large crockpot on the ‘keep warm” setting and the lid cracked to keep the temperature lower. But the process takes weeks, so I also bought some finished black garlic ready to use. If you go in for this cheat, you have the option to get the Asian kind that is one single huge clove of garlic about an inch across as shown above, but if you buy from Black Garlic North America you can buy it peeled fairly economically or (my choice) you can buy 1.5 pounds unpeeled and have the skins available to put in simmering chicken stock, giving it wonderful depth.  It is also sold in tiny little packets in many grocery stores, but I do not recommend that form. It is often dried out and unpleasant by the time you get it when it should be moist, chewy, and have the complexity of good balsamic vinegar with a different flavor.

As for using it, one of my favorite simple uses is to pound two huge single cloves or 5 to 6 regular cloves of black garlic to a smooth paste in a mortar and pestle with a little salt, then pound in 2 tablespoons of cold butter and a teaspoon of very good balsamic vinegar (nothing from the grocery store.) Pound until you have a smooth mousse-like paste, then use it to top steaks, spread it on bread, or toss with a little pasta. To make the heavenly sauce above is only slightly more complex. Make the black garlic butter paste as described. After pan-grilling a nice bit of steak, while the steak is resting deglaze the pan with water or red wine, boil down the fluid hard, add a cube of beef glacé from the freezer, and when the glacé is melted, add the black garlic paste and stir in thoroughly. Add a little water to thin the sauce to desired consistency, taste for salt, slice the steak, and pour the sauce over the slices.  This amount of black garlic paste makes enough for two people.   The recipe is very adaptable and doubles easily.  It’s rich and meaty, full of umami, and enhances everything it touches.  Tart it up with some extra butter if you want it even richer.  It also does wonderful things for ordinary supermarket cremini  mushrooms, and even better things for more flavorful mushrooms like shitakes.  Needless to say, make beef glacé if you don’t have it, and don’t even think about using a boullion cube. Or pound out the garlic cloves without adding the other ingredients and put them in vinaigrette.

Above, several regular-sized  cloves of black garlic were pounded and roughly mixed into half a cup of red wine vinaigrette and spooned over cold sliced steak, sliced avocado, and salad.  This might sound like too much but the flavor of black garlic is mellow and surprisingly low-key and you need a lot when it’s the main flavoring.

I was rather startled to find that all kinds of miraculous health benefits are attributed to black garlic, to the extent that it is sold in capsules for people who want to take it more conveniently. That anything as meaty and delicious as black garlic should be ground up and put in capsules is weird to me, sort of like taking steak in capsules, but suit yourself.

Incidentally if you grow a lot of garlic and have trouble storing it through the winter, it might be worth rigging up a chamber so that you can make black garlic in quantity. I would imagine that it could be sold quite profitably at farmers markets, since I almost never see it in those venues. However, I am nowhere near handy enough to tell you how to make a 140 degree chamber without burning down your house. Know your limitations.

‘The ”other goodies” refers  to the fact that the same process can be used to blacken some other foods, with varying results. Please use the Noma people as your guide if you want to try this, since I am experimenting with it but my products are not ready yet. Their descriptions of apples blackened in the fermentation chamber, then dehydrated until chewy, then coated in very dark chocolate, sound luscious. I am blackening some quinces, and I’ll report back if the result is worthwhile.
