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.

The Greens of Winter: Soup Base

img_5098

Earlier this week I walked through my frost-killed garden to see what was left. For the most part I don’t make any special effort to protect my garden in the fall because after a long summer I’m ready to move on to the things I do in the winter, so the pickings were slim, but I found lots of chicory, dandelion, chard, broccoli leaves, alfalfa tips, celery, and kale, along with green garlic and green onions, and some of the herbs were still in fine shape. I decided to make soup, and since I had a lot more greens than I remembered planting, it occurred to me to make a soup base that could sit in the freezer, ready at any time to be turned into soup in a hurry. To the garden ingredients I added a large onion and a largish handful of sun-dried tomatoes from earlier in the summer. You could also use a jar of dried tomatoes in oil, drained.  The celery was used from base to leaf tip. I used roughly equal volumes of all the greens types, about the equivalent of a medium-sized supermarket bunch of each.

The onion was sliced thinly and sautéed very slowly in olive oil while I washed and prepared the greens. I was aiming for a rich caramel color, which meant low heat and frequent stirring, which is no extra trouble if you’re in the kitchen anyway. I used my wok because I knew that the volume of sliced greens would be considerable. First the green garlic and green onions were cleaned, finely slivered, and held separately, then everything else was washed and midribs removed and cut in cross section into roughly 1/2″ slices.

When the onion was a nice toffee color I added the chopped green alliums, cooked about another five minutes, then added the other greens and some more olive oil along with about a teaspoon of salt. Don’t stint on the olive oil. You want sautéed flavor, not steamed flavor.  The heat was turned up to medium and the whole mass stirred and turned with a wide wooden spoon about every five minutes to keep it cooking evenly. As soon as the greens were in the pan I ground the sun dried tomatoes into small powdery chunks in the blender and added them to the wok. They rehydrated well enough in the moisture from the leaves.  Keep cooking until the greens are soft when chewed.

When you have a darkened dense mass of soft greens, put the whole business in the food processor and grind to the finest paste that you can achieve. Taste. You want it on the salty side, because that helps with preservation and it’s going to be diluted later. Add more salt if needed. I prefer to use fish sauce rather than salt to season at this point because it adds a wonderful rich savor. I used about a tablespoon. Don’t use this if you might be serving vegetarians.

Now cool your soup paste and pack it into one-cup containers, each of which makes about a quart of finished soup. Coat the top with olive oil, push lids on tightly, and freeze.

When ready to use, put a quart of any kind of salt-free or low-salt broth you like in a saucepan, add a cup of soup paste, and simmer until thawed. Correct the texture with a stick blender if it needs smoothing out. Taste for seasoning and adjust in any way you like. The caramelized onions, deeply sautéed greens, and fish sauce gave a meaty-umami flavor to the potful I made for lunch today, so I salted to taste and added a swirl of fat from my homemade bacon and a generous sprinkling of thyme leaves, a meaty-umami herb if ever there was one. Yum. With toasted buttered slices of my low-carb fake-o cornbread, it made a perfect light healthy Thanksgiving brunch to lead into the excesses to come at dinner.

This basic formula can be varied endlessly according to what you like and have available. If you serve vegans at your table, using some miso rather than fish sauce and good olive oil for the final swirl with water or vegetable broth as the liquid would suit their needs while fully satisfying the omnivores. If you don’t like the brownish color, leave the tomatoes out and it will be more green. Pan-grilled small oyster or other mushrooms would make a good garnish. A fried or poached egg adds tremendous heft to soup if you want a richer meal, or some bacon lardons fried crisp would satisfy any ardent carnivore with a minimum of actual meat. You can add cow or coconut cream for a cream soup (try a toss of chopped fresh tarragon for the final garnish,) or some leftover tomato sauce for interesting tartness, or finish it with a handful of good freshly grated Parmesan along with olive oil and let the cheese dissolve in the hot soup. For a more Cretan effect, use crumbled feta and olive oil on top.  There are a hundred possibilities and you can get any of them from freezer to table in well under 20 minutes. Serve any kind of bready stuff that suits your diet alongside, and you and your table mates will be full. I say that a quart of soup is two servings, but I understand that normal people can serve three or four with a quart. Know your family’s tastes.

In my opinion the celery is necessary rather than optional, and I strongly advise including at least a small portion of bitter greens (dandelion and chicory in this case.) When making mixed greens, I’ve often noticed that a savory-meaty element is lost if I don’t include some bitter greens. The proportion is small and the final product isn’t bitter and is enjoyed be people who don’t like strong greens in other contexts. Besides, they’re so damn good for you.

A Glory of Greens, and notes on Turkish greens soup

image

 

There is nothing more vibrant than a garden full of greens in the spring, all growing like mad, offering you a million healthy possibilities. During the two unfortunate years that I couldn’t garden, I did at least rogue out all the weeds that weren’t edible, and now nearly everything that sprouts in my beds is delicious, whether I planted them intentionally or not. And everybody, every one of us, would do well to eat more greens. Our health would improve and we would feel so damn good. Remember, the REAL Mediterranean diet, the one that was originally studied on Crete and that produced a long-lived and healthy population, was based on a huge variety of cultivated and wild greens.

Today I noticed nettles, spinach, and lambs-quarters that needed to be harvested pronto. I also had lively green garlic ready to harvest. I picked a three-gallon pail to the brim, but loosely filled as I threw the bounty in, not packed down. I washed them ( it goes without saying that when nettles are in the mixture, you use gloves whenever handling them and stir in the washing water with a big wooden spoon, not your hand,) and decided to make a Turkish greens soup for dinner.

This is a soup that I have been making variations of since a lovely trip to Turkey nearly thirty years ago. It is based roughly on a soup that my guide described his wife making, but it’s interpreted by me and changes every time I make it, so I don’t vouch for its authenticity. This time it was a thick velouté; other times it’s a rough potage, and sometimes it resembles gumbo z’heirbes. So here’s how this one happened:
Prepare and wash three gallons, loosely packed, of assorted greens. No bland store-bought baby spinach! If you don’t have a garden, consider chard, adult spinach, and Tuscan kale, one bunch each.
Pull a quart of good rich chicken stock out of the freezer (it is in there, isn’t it?)or procure a quart of good chicken stock from somewhere.
Set the chicken stock to melting over medium heat in a gallon pot.
Chop three large stalks of green garlic, stems, leaves, and all, and sauté them in a quarter cup or so of excellent olive oil in a sauté pan. OR use a small onion and two cloves of garlic, chopped, for the sauté step. Make sure they are cooked through, and soft but not colored, before proceeding.
When the garlic mixture is ready and the stock is boiling, begin adding the greens to the stock, stirring, and remembering not to touch those nettles. Boil for about a minute after the last of the greens is added. Now add the garlic mixture to the soup pot and simmer for five minutes.
Now purée with a stick blender. Add salt to taste (I think it needs to be on the salty side)and add a teaspoon of Urfa pepper flakes, Aleppo pepper flakes, or mild red pepper flakes. I like a bit of oregano and thyme. Taste and correct the seasoning carefully.
Mix some full-fat Greek yogurt with salt to taste and have it ready.
Put six egg yolks in a bowl, whisk them up, and slowly add a cup of the hot soup, whisking furiously all the time. Slowly pour the egg mixture into the soup over lowest heat, and whisk another minute or two until it’s lightly thickened and smooth.
Serve into bowls, pile a half cup of salted yogurt in each bowl, drizzle lavishly with your best olive oil, and sprinkle heavily with more Urfa or red pepper flakes. Eat, and flourish.

Kitchen Staples: Broth


Few things will improve your cooking as much as getting rid of all commercial broth products and making your own. On my website I have extensive notes about broth-making, and you can read them here. In this post, I’ll just add a few notes about broth and its uses, and refer you to that site for the details.

Use very good materials to begin with. You can get lovely flavorful pastured chicken necks and backs from Pollo Real at the Santa Fe farmer’s market, and there is no better basis for chicken broth. Give the roasting step the time it needs, and the pay-off in flavor will be considerable. Don’t salt your broth, because you may want to reduce it later which will concentrate it manyfold. I pressure-can mine for later use, but if you have room in your freezer, that’s an easier alternative.

Once you have good broth on hand, you can use it to reduce waste and pick up some goodness from all kinds of things that you might otherwise discard. If I buy a pound of oyster mushrooms or shitake mushrooms to roast for a winter dinner, I put the stems and trimmings in a quart of broth to simmer for an hour, building the foundation for a great mushroom sauce or mushroom soup on another day. Chicken bones left over after dinner? Pop them in a quart or two of broth to simmer and enrich the flavor. Onion skins and ends on your cutting board? A slow simmer in broth will improve its flavor and give it a lovely gold color, and the rawness of the onions is lost en route.Many people save their bones and vegetable trimmings in plastic bags in the freezer, but I think the flavor is better if you simmer them while they’re fresh. The broth can be frozen more successfully than the ingredients.

Fish and seafood broths need to be cooked separately from other meats, naturally, and don’t include any salmon trimmings. I love salmon, but it does ruin fish fume’. But if you buy a few mild fish heads to start fish broth, then every time you have shrimp shells, crab shells, or any other flavorful but inedible seafood bits available, you can extract its flavor in broth and save the broth for a great paella or gumbo when you’re in the mood.

Once some good enriched broth is hanging out in your kitchen, what do you do with it? There is almost no pan-grilled or roasted meat that can’t be improved by a simple reduction sauce. Remove the meat from the pan, pour a cup of good broth into the pan over high heat, boil hard and scrape all the lovely browned bits into the broth, and when it’s reduced to a few tablespoons and has a syrupy consistency, swirl in a tablespoon of butter and serve immediately. A glug of good red or white wine, depending on the meat and seasoning, can be added to the pan for the initial deglazing, then add the stock and boil down. If you want to get fancier, most of the sauces of classic French Cuisine are at your command when you have really good broth to start with, and you can check out Glorious French Food or another cookbook to consider your options. Grains like rice and bulgur are delicious when ccoked in broth. If you’re a fan of Mexican cooking, you’ll want to try Zarela Martinez’s trick of toasting dried chiles of various kinds and then soaking them in broth rather than water before grinding them into a mole’ paste or other flavoring paste. Great stews like coq au vin are within your reach, although they will use up a lot of broth, which is why you make a lot in the first place. A paprikash like the one above requires little more than a meaty main ingredient, top-notch paprika, and really good broth (my own far-from-conventional recipe is below.)When I’m feeling dispirited and glum I revert to my Louisiana roots and make gumbo, and it invariably cheers me up, and usually cheers some other people too.

I advise avoiding strong-flavored vegetables of the cabbage family, such as broccoli and kale, for general-purpose broth. If you use leafy greens, they will color the broth, so don’t use them unless you’re willing to have green broth. Onions, carrots, celery, shallots, and leeks are aromatic staples that improve any broth. If you want to make all-vegetable broth, my favorite way is to roast the vegetables to bring out their flavor via the lovely Maillard reactions, and add a few mushrooms for the base note; dried shitakes are especially good for this, and as long as you don’t use too many, the flavor will not be identifiably Asian. .

If we can grasp some positive principle from the wretched ecomony, it should be to get the best value we can from everything we use. Nothing does that better or more gracefully than broth.
