Fermenting Fantastic Food

Basic Milk Kefir

Kefir (pronounced KEE-fur or Kay-FEAR, depending on your preference) is a drinking yogurt that is bursting with probiotics.  In the past few years, it has become a grocery store staple here in the US, but it is ridiculously easy to make yourself.  Besides the obvious cost benefits, there are the added benefits of DIYing, such as choosing the quality of milk you want, knowing your bacteria are the real, live deal and making whatever “flavors” suit your palette.

There are a couple of tiny hurdles to overcome before you make kefir.  First, you need kefir grains.  If you don’t know a hippie or a fermenter, you can order them online.  I got some from Cultures for Health to test them, and after rehydrating, they worked just like the grains I got from a fellow fermenter.  GEM Cultures sells fresh grains that also work like a charm, without the pesky need to rehydrate them.  I like the idea of getting them from a person, because it creates community and as any kefir maker knows, you will eventually have way too many grains to know what to do with, even after you make a batch dedicated to kefir sour cream and try some in non-dairy milks and unpasteurized juices. So getting them from a friend prevents waste, too!  If you live in Philly, I am HAPPY to provide you with extra grains.  Just shoot me an e-mail or post it in the comments.

Second, kefir grains and metal don’t mix!  Just like with your kombucha SCOBY, you can actually harm your grains by putting them into contact with metal.  This means you need a non-metallic fine mesh strainer (mine cost $1.99 at my local kitchen supply store) and something to stir your grains with.  I usually use the rounded end of a chopstick.  If you kefir or store your kefir in a canning jar, it might be a good idea to get plastic caps to minimize the risk that your grains will touch metal, and the risk of corrosion.  You certainly do not need to use a canning jar to make your kefir.  I’ve used everything from half-gallon glass milk jugs to pyrex bowls.  The only important thing is that you are able to easily secure a cover to your container.

Third, the most important variable here is temperature.  Your grains will kefir best at room temperature.  Below say, 68 degrees Fahrenheit, fermentation will get very slow which isn’t super for milk kefir.  Above 78ish, it will kefir too fast which can throw the balance of your bacteria and yeast out of whack.  Do not leave your grains in for longer than 24 hours.  If your milk hasn’t kefired by then, strain out the grains and discard the milk.  Try again.  I have literally never once had this happen, but in colder months, I’ve had to wait a full 24 hours for a batch to complete.

A grain against the grain

“Recipe” (quotes intentional):

1 Tablespoon of kefir grains

1 pint to 1/2 gallon of your preferred milk

  1. Put kefir grains in container
  2. Attach covering
  3. Move container to a room temperature spot out of direct sunlight
  4. Gently agitate when you remember to
  5. When milk is thickened (anywhere from 12-24 hours later) and smells a bit yeasty, strain the grains out of the kefir, put them into fresh milk, and stick the grain-free kefir into the fridge
  6. Begin process again*

*If you have made enough kefir, you can keep your grains stored in milk in the fridge for up to a week before starting your next batch.  Even at the low fridge temperature, the milk will kefir, albeit very slowly, so be sure to start your post fridge batch at a time when you will be able to watch closely.

Puttin’ all kinds of strain in that grain you got

Kimchi

Mild and tasty

Making kimchi, at least the way I do it, is super fun and easy.  We eat it most days at our house.  It’s great on egg and pasta dishes, and our casual party favorite mac and kimchis. We eat it in alone, in small quantities, and it is fantastic as a filling (mixed with some kind of protein such as beans) on top of a sourdough crepe.  I also use it in ways that other people probably find disgusting, such as mixed with cottage cheese or on a veggie dog.  But, I digress.

The great thing about kimchi is that it’s flexible and you can sub what you’ve got.  I’ve used regular cabbage instead of napa, french breakfast radishes instead of daikon, and I’ve used leeks and/or red peppers and tons of other stuff I’ve pulled out of my garden or the off the stands at the farmer’s market.  All-radish kimchi is traditional and so good!  I’ve made it so spicy my spice-loving husband teared up and so unspicy my bland-loving friends and relatives raved.  YOU CAN USE ANYTHING.  Anything!  Except tomatoes, cukes and squash which would mush.  It’s going to taste delicious regardless of your vegetable choices so play around.

A note: generally when working with ferments, metal is not your friend.  You won’t kill your kimchi like you would your kefir grains or your kombucha scoby, but as a habit, wooden or plastic utensils are better to use.  During long fermentation, any metal in your container could corrode due to the lactic acid that is being produced.

Here’s my basic recipe to get you started, but remember, it’s up to you to make it taste how you like it to taste!

Basic, Flexible Kimchi (Adapted from Sandor Katz’ Wild Fermentation and the Art of Fermentation, The Kimchi Chronicles Cookbook by Marja Vongerichten and myriad YouTube videos over the years)

Ingredients

Makes one quart

1 – 2lb head napa cabbage, skanky outer leaves removed and reserved

1 large daikon

1-2 bunches of scallions (or Korean chives if you can find them)

3 large carrots, julienned (optional)

1 leek, thoroughly soaked to remove debris and sliced (optional)

1 red or yellow bell pepper, sliced or chopped into 1/2 inch squares (optional)

4 T salt (possibly more)

1/8 c rice flour (or a chunk of fruit, equaling about 1/3 c.  Stone and tropical fruits work great!)

3 inches ginger, unpeeled, or to taste (I use more)

4 cloves garlic, or to taste (I use more)

1/2 an onion

2 T red pepper flakes

1/4- c gochugaru (Korean red chili powder) (omit this if making a white kimchi)

 

The Process

  1. Thoroughly rinse cabbage, daikon, carrots, leek and bell pepper.  Chop cabbage, discarding core.  Put it in a big bowl full of room temperature water.  This is to remove any excess dirt and debris.  Rinse after 10-15 minutes of soaking.
  2. Chop carrots, daikon, leek and bell pepper according to preference.  Most traditional is larger pieces of cabbage and matchsticks of other veggies.  Put chopped veggies in a large bowl. Add rinsed cabbage.
  3. Mix salt into 8 cups of water (or more if needed) until dissolved. Pour over chopped veggies.
  4. Submerge veggies under brine using whatever you have that fits. I use a plate.  Cover container with a large cloth and secure with a rubber band. Let sit overnight or up to 24 hours.
  5. After vegetables have brined, mix rice flour with 1 c cold water until dispersed.  Put in a small pot over low heat.  Stir constantly, 3-4 minutes, until mixture has thickened.  Remove from heat and let cool to room temperature.*
  6. While the rice mixture is cooling, start prepping the other paste ingredients.  Coarsely chop ginger. Cut out any questionable parts, but do not peel.
  7. Coarsely chop onions, scallions and garlic.
  8. Place ginger, alliums and red pepper flakes into food processor and blend into a paste.** (If using fruit instead of rice paste, blend that up, too)
  9. Once rice is room temp, mix together your allium/ginger paste, your rice gruel and your red pepper powder.
  10. Strain brined veggies.
  11. Mix together veggies and ginger/allium paste until veggies are well-coated.
  12. Press them tightly into a jar (or other container that you could compress them into) and make sure they stay submerged. (We’ll discuss a couple methods for this).
  13. Put them in a place out of direct sunlight, away from other ferments and that has a consistent room temperature (above 68, below 80).
  14. Let them sit for 3-7 days, but for your first solo batch, feel free to start tasting at 3 days to see when it hits your flavor preference.  When it’s done, stick it in the fridge.  That will slow, but not stop, fermentation, so your kimchi will be more sour if you pull it out of the fridge in a month than it was when you put it in.

*If using fruit for your paste, skip this step

**If using fish sauce and/or shrimp paste, you would add it here. 1/8 c or to taste fish sauce.  One T shrimp paste or a few tiny salted guys, added at the hand-mixing stage.

Brining veggies

 

Kimchi, with brining veggies in the background

In the US, kimchi usually means one particular kimchi recipe that contains cabbages, radishes, ginger and spice.  There are many other traditional kimchis and even more recipes made in individual homes.

**You can let this ferment as long as you’d like.  Start tasting at 3 days, but if you like it a bit more acidic, keep it going.  According to “The Art of Fermentation” by Sandor Katz a study conducted in Korea found the ideal fermenting time for kimchi is 3 days, due to changes in the type of bacteria that thrive during early and late fermentation.  I usually try to leave mine a few days more but we are generally too hungry for kimchi to leave it much longer.
