Kimchi making!

J and I were running low on kimchi. The last batch was from 3 or 4 months ago, so we go through about 1 quart per month. College friend S was interested, so we all got together to make kimchi!

We used Maangchi’s recipe, omitting the minari (dropwort) and the Asian chives, and substituting bonito flakes for the brined shrimp. This time, we also decreased the red pepper flakes to 1 cup. We didn’t have enough Korean red pepper flakes, so I substituted cayenne pepper powder for the remainder needed.

So much cabbage! It weighed about 7 lbs.

In addition to Napa cabbage (tongbaechu) kimchi, we tried making green onion (pa) kimchi. J really likes green onions 🙂

As usual, the kimchi turned out deliciously. It is much more edible this time around, thanks to halving the amount of red pepper in the recipe! The key to the flavor is the fish. Without it, the kimchi tastes bland (not enough umami); if you get it wrong, it tastes horrible. There was a memorable batch of kimchi several years ago where I used Thai shrimp paste that unfortunately smelled like rubber…

We got about 1.5 gallons kimchi, some of which will be going to friend S for her help! I added extra water to the jars to make sure the cabbage was submerged…bad idea. The CO2 produced by fermentation caused all but two of the jars to spill by the next morning.
Here’s the finished pa kimchi!

Out of curiosity, I looked up what bacteria are present in kimchi.

The picture [the experiment] paint[s] is that the microbial population changes fairly radically over time. At first, the cabbage, which was soaked in brine, drained, and mixed with a variety of seasonings, was populated mostly by unidentified bacteria and ones from the Deferribacterales group, whose representatives have cropped up in oilfields and in the guts of deep-sea shrimp. These bacteria may have been on the cabbage to begin with, rather than having anything to do with the fermentation, because as the days passed, and the oxygen ran out, others began to take over.

By the seventh day, DNA from the Leuconostoc group, which converts sugars into lactic acid and are behind the fermentation of kefir, a fermented milk drink, and sourdough bread, was on the rise. By day 13, members of the Lactobacillus and Weisellagroups had joined in. Like Leuconostoc, Lactobacillus andWeisella produce lactic acid from sugar, and they’re also part of the team behind cheese, kefir, pickles, and other fermented products. Together the three groups dominated the kimchi for the rest of the experiment.

And I discovered that there’s a fermentation subreddit for all your fermentation needs! (The top post at the moment is titled “The number one mistake fermentation newbies make is paranoia“!)

Thinking of making alcohol

Neither J nor I really drinks alcohol. We use it, in the form of mirin and sake, for cooking. So I’ve been thinking of trying to make sake. A similar process is used to make rice vinegar.

Generally speaking, sake is made by fermenting rice. Amylase is used to break down the starches in cooked rice into simple sugars. Yeast ferments the sugars into alcohol. Then there are a few filtration steps, to remove the half-digested rice chunks and clarify the liquid.

More specifically, the amylase is provided by koji (Aspergillus oryzae, used as well for soy sauce, miso, makgeolli, shouchuu, etc) in modern sake production. The yeast is a specific cultivated variety or varieties. The sake is clarified using activated charcoal. This is the best article I’ve found describing in detail how to make sake. Here’s another that might be easier to follow.

However I’m not interested in “proper” technique. I especially don’t want a fussy recipe where I have to buy things. I’d rather use materials I have on hand or that are available for free (like wild yeast).

So, there are less exacting traditional techniques that can be used. The amylase can be provided by saliva, as in the production of kuchikamizake (as seen in Kimi no Na wa). And the yeast can be wild, as in sourdough. I also suspect that you can use barley malt (leftover from making gochujang) for the amylase. After all, it’s used in other alcoholic beverages.

So, I’ll probably do some low-volume experiments with kuchikamizake, barley malt, and koji, of which I have a very small amount. We’ll see how it goes!

Vinegar-making

When friend S was over for kimchi making, we started talking about other foods we could make. It seems like there’s the most collective interest in vinegar and in alcohol. ( I’d like to make hard cheeses in the future as well.) So I embarked on some initial vinegar experiments!

According to this source, all you need to do is inoculate an alcoholic liquid with acetic acid-producing bacteria. Some other sites suggested adding sugar, to provide easier-to-access food. You can get the bacteria from unpasteurized vinegar (e.g. Braggs brand), but I figured I would try inoculating with kimchi juice, since it’s sour. I’m not sure what acid is in kimchi. Some of it is lactic acid, but there might be acetic acid as well.

So I mixed together some kimchi juice (1 part), a pinch of sugar, and sake (5 parts) in a little glass jar. I guess I’ll just let it sit and see what happens. I wonder if the sake is too alcoholic. It’s surely possible to kill off all the bacteria.

I also discovered a vinegar subreddit (I’m not even surprised at this point). If you just looked at this, you’d think that everybody’s making their own vinegar!

Waffle Iron!

We got an early 1950s waffle maker from a garage sale!

It looks like this.
And it looks like this when you close the lid. It has a light that turns red when it’s on (it’s actually just the glow from the heating element).
Here’s some info I dug up about the machine. It’s reputedly “as bulky as a Buick.”
It transforms into a grill if you fold it down and take off the waffle grates.
After seasoning the cast iron, we made waffles! 
It’s pretty nonstick!
The finished waffles, only slightly burnt.
For dinner we made monjayaki using the griddle mode. It’s was great!

Gochujang recipe

There aren’t a lot of gochujang recipes online (in English). They don’t explain what you’re doing and why you’re doing it, so it’s hard to tell if it’s working. Because gochujang takes several months to ferment, I wanted to be extra sure that it would work. So I combined three different recipes with some advice from the beer-brewing community. Of course I started with Maangchi’s recipe, but I also consulted this video and Eating Korean. I’ll give you the recipe I ended up using, with some explanation at the end of what we’re doing.

Assembling ingredients for gochujang

J and I recently ran out of gochujang, a spicy fermented red pepper paste ubiquitous in Korean cooking. Since I’ve been trying more than usual to not buy things in plastic packaging, I was hesitant to buy a new container. (Although Wholly Jang offers gochujang and other products in glass, the company is currently on hiatus as they move to a different facility.) Fortunately, I discovered that you can make your own at home with just a few ingredients!!

My mom’s potato bun recipe!! Delicious!

Now that I’ve worked the kinks out of my mom’s bun recipe (the first version she sent had a few typos in it…), I can share it with you! These buns are delicious– slightly sweet, moist, fluffy. Even when I substitute a ton of the ingredients, they still turn out completely fine!

Refrigerator Potato Buns (makes 24 rolls)

1 1/8 tsp yeast

3/4 cup water

1/3 cup sugar

1/4 tsp salt

1/3 cup butter, softened (1/4 cup butter can be used for lower fat)

1 egg

1/2 cup mashed potatoes

1/2 cup rolled oats

3 1/2 cup bread flour (Start with 3 cups. Reserve 1/2 cup for adjusting the texture of the dough.) Continue reading “My mom’s potato bun recipe!! Delicious!”
