What’s Fermenting: Beet Kvass

As I write this, it is one week before Christmas Eve, 2021. COVID-19 is once again booming in New York City, and we are once again in “hunker down” mode. This year, we will have a quiet Christmas at home. For a few years now, we have been doing our own personal take on a traditional Polish Christmas Eve dinner, which is known as the Wigilia (from the Latin for vigil). The Wigilia is by tradition a pescetarian meal, which is perfect for us, and gives us an excuse to whip up some of our favorite Polish dishes, especially pierogi.

But the first course of a Wigilia, and in some ways, the centerpiece of the meal, is Barszcz, a clear, beautifully red, slightly sour, beet broth. The broth is served with uszki, or “little ears,” which are similar to small pierogi, but stuffed with fragrant dried Polish forest mushrooms. (The barszcz itself is typically vegan; the uszki typically have egg in the dough, but are otherwise vegetarian.) A few years ago, I got my Mom’s recipe, and it is in her customarily minimalist style:

Barszcz 

  • 1 pound beets, wash, cut in quarters
  • Veggie stock
  • Apple cider vinegar, normal vinegar, or squeezed lemons

(All of my Mom’s recipes are like this. In order to make sense of them, you will have had to seen them prepared, and of course, tasted them many, many times. We’re fine on both counts.)

The hint of sourness is really the key to this dish. Since we are both fermented foods enthusiasts, two years ago we hit upon the idea of using one of our own ferments in place of vinegar. The prefect candidate was beet kvass, which is quite simply the brine from fermented beets. It gives the sour kick, delivered with an intense beet flavor. The recipe and method are pure simplicity.

Beet Kvass

  • Farmer’s market beets, topped & tailed, washed, not peeled
  • 3.5% salt brine

Halve or quarter the beets, and fill a large mason jar. Fill the jar with the salt brine, ensuring all beets are under the brine. Cover with an air-tight lid, or airlock. Let ferment, checking periodically for pressure build up—opening the lid once or twice a day should be fine.

As with any fermented food, the key to success is to start with very fresh, high quality produce. Nora got our beets from the Fledgling Crow Vegetables stand at the Dag Hammarskjold Plaza Greenmarket. (They were a little surprised that Nora wanted 7.5 lbs of beets!)

With just one week to ferment, our kvass will probably be on the mild side, but we can keep it going for weeks or months more. Nora likes to drink a bit of it in seltzer water as a savory tonic.

Recipe: Vegan Sichuan Inspired Celery Stir Fry

Thanks to COVID-19 era food shopping, we are finding ourselves with huge amounts of certain ingredients. Right now we have about five bunches of celery! We saw a great idea for Sichuan celery on Ruth Reichl’s Instagram. That made me think of one of our current favorite recipes, which is Diana Kuan’s Vegetarian Mapo Tofu. I improvised a bit with Kuan’s recipe and came up with this recipe for the celery stir fry. It was amazing! 

Ingredients 

  • 12 dried shiitake mushrooms  
  • 1 cup warm water  
  • 2 tbsp fermented black beans  
  • 2 tbsp olive oil  
  • 3 scallions, sliced, white and green parts separated   
  • 2 tsp minced ginger  
  • 6 stalks celery, trimmed and chopped 
For the sauce 
  • 2 tbsp gochujang  
  • 1 tbsp aji mirin  
  • 2 tsp soy sauce  
  • 2 tsp sesame oil  
  • 1 tsp ground Sichuan pepper 

Method 

Soak the shiitakes in the warm water for 15 minutes. Retain the soaking liquid for the sauce. Stem and mince the shiitakes (retain the stems for stock). Rinse the fermented black beans, and mash them with the back of a spoon. In a small bowl, mix together the sauce ingredients, adding a few tbsp of the shiitake soaking liquid, set aside. Heat the oil to medium high. Add in the white parts of the scallions and the ginger. Stir fry for one minute. Add in the minced mushrooms and fermented black beans. Stir fry for two minutes. Add in the celery and stir fry for a few minutes. When the celery is close to done, stir in the sauce. Set heat to high until the sauce begins to boil. Lower heat and reduce sauce. Serve in a bowl covered with the green parts of the scallions.

TriBeCa: Lekka Burger

Amanda Cohen, at the helm at Dirt Candy, is arguably NYC’s top vegan chef. When we heard that she was opening a vegan burger joint in TriBeCa, we were thrilled! Today we got to try it. The restaurant is called Lekka Burger, and it’s at 81 Warren Street, right around the corner from Sonic Youth’s old studio on Murray Street.

The menu features five different burgers, fries with various toppings, salads, shakes, and a bar. The burgers are Cohen’s own secret recipe. They’re quite delicious, earthy, mushroomy, umami-y, with a satisfying heft and texture. The sides were great, and we loved the mango oat milk shake–we’ll try vanilla with a shot of bourbon when we go back for dinner.

Cohen’s partner in Lekka is South-African-born philanthropist and climate activist Andrea Kerzner. The team’s focus on zero-waste is evident; merchandise sold in the store benefits Grow NYC. It’s also a nice room with a friendly vibe. We can’t wait to come back!

What’s fermenting: Easy Homemade (Vegan) Kimchi

You might say I caught the fermentation bug from kimchi.

Salty, spicy, sour, with a slightly crunchy edge, this staple of Korean cuisine makes a deliciously addictive addition to everything from fried rice to tacos to sourdough pancakes to grilled cheese sandwiches.

You can buy small jars of artisanal versions for upwards of $10. I’m here to tell you it’s easy–and satisfying–to make at home.

The active prep time is minimal. But with all the resting/fermenting required, it’ll be four days at the very least until you have kimchi that’s ready to eat. The ingredients are: Napa cabbage, daikon (Japanese radish), scallions, ginger, garlic, salt, sugar, plus a Korean a hot red pepper powder called gochugaru (available at specialty stores such as Kalustyan’s here in NYC and also online). Traditional non-vegan recipes include fish sauce and dried shrimp.

Kimchi relies on the same probiotic (human-friendly) bacterium for its fermentation as sauerkraut: lactobacillus acidophilus. The bacteria are naturally present on the cabbage leaves and just need a little encouragement. That encouragement comes in the form of salt and being packed tightly in a container deprived of oxygen. Both of these things kill off the competing (human-unfriendly) bacteria, giving the lactobacillus acidophilus freedom to take over. (If you’re interested in reading more about the subject, I highly recommend books by Sandor “Sandorkraut” Katz.)

I made my very first batch of vegan kimchi three years ago. I’d never tried my hand at making any fermented foods before and, to be honest, felt a little apprehensive about adding dried shrimp to something that was going to be sitting unrefrigerated on my kitchen countertop for over 24 hours. Plus shrimp and the fish sauce were just another two ingredients I’d need to buy. I decided to try a vegan recipe instead, and found a great one from J. Kenji López-Alt at Serious Eats. It’s possible to simply skip the seafood and leave it at that. But he substitutes miso paste to give the finished product extra tasty umami depth.

I’m a much more confident home fermenter now, but am hooked on this vegan version of kimchi (one day I’m going to try the shrimp). I make it regularly, and over the years have adjusted the ingredients and prep method slightly to my preferences. Traditional recipes call for whole Napa cabbage leaves–or, for larger batches, an intact, whole head of it, with the seasonings packed between the leaves (cool video here). But I found tearing the leaves into smaller pieces made them easier to handle every step of the way. They were easier to salt, easier to mix with the chili paste, and easier to pack in–and pull out of–jars.

I also learned the measurements don’t need to be exact. If you only have three scallions on hand instead of six, three scallions will do just fine. Same goes for garlic and ginger–and the hot pepper. You even have some leeway with the amount of salt. As for the countertop fermentation, 24 hours is a basic minimum, but in cooler weather I let it go for about 36. The kimchi will get more and more sour as the process goes on. Once it’s in the fridge, fermentation will continue but at a much slower rate. Feel free to adjust to your own tastes.

Vegan Kimchi

(adapted from J. Kenji López-Alt at Serious Eats)

  • 1 head of Napa cabbage (1-2 lbs)
  • 2-3 tablespoons non-idodized salt (kosher or sea salt)
  • 6 scallions, trimmed, greens separated from white parts, and cut into 2-3 inch lengths
  • fist-sized piece of daikon (Japanese radish), peeled and cut into matchsticks approx. 1/4 inch thick
  • 5 cloves garlic, peeled
  • 2-inch knob of fresh ginger, peeled and chopped coarsely
  • 1/2 cup gochugaru (Korean red pepper powder)
  • 2 tbs miso paste (I used low sodium)
  • 1 tbs sugar (I used dark brown but any kind will do)
  • water

Remove core from bottom part of Napa cabbage. Tear leaves into small pieces and place in a large bowl. Add scallion greens and daikon matchsticks. Add salt a little at a time to bowl, mixing to distribute among the leaves. Cover with a cloth and allow to wilt for 6-12 hours. Stir as needed to redistribute salt. The vegetables should release 1/4-1/2 cup water.

In a food processor, combine scallion whites, garlic, ginger, gochugaru, miso, and sugar. Whir for a few seconds to form a coarse paste.

Combine paste with the cabbage mixture in a bowl. Add 1/4 cup of water and either stir with a spoon or knead with hands until the paste is evenly distributed. Taste for desired saltiness and adjust as necessary. Pack into a large jar, pressing down with the back of a spoon to release any trapped air pockets and allow some liquid to rise to the surface until the vegetables are completely submerged. Tighten lid on jar.

Allow to sit at room temperature 24-36 hours. Open jar after 12 hours or so to release gasses. Place in fridge. Can be consumed in 48 hours and keeps for a month or two. Note: Kimchi will become softer and more sour as time goes on.
