Looks good Bionut did you add spores or let natural ones take? How is the soy going now? Mine is still sunning away it seems to be getting darker, not sure will have to take a picture and compare to the one from awhile ago as I look at it daily. The sludge in mine is still fermenting slowly. Wish you luck and look forward to how it turns out.

I did not added spores. My cookies aren't in brine yet, i had to dry them before that. I think that today i will make some brine and add the soy cookies.

Hello and greetings from Indonesia,

Thank Goodness i found this forum.

I'm interested in making my own soy sauce, just buy some soy beans and still soak them for overnight before cook'em. As tropical country, sun and humidity is ideal to make soy sauce. Here we have our unique soy sauce called "Kecap" (just like ketchup pronounciation). There are two varieties, Sweet (Kecap Manis) and Salty (Kecap asin), basicly use black soy bean, palm sugar, garlic, cinnamon, star anniseed, etc. But unfortunately i don't have any relative who related with traditional kecap factory. i let you know when i get some information.

 

A lot of traditional kecap factory closed because of no more market, no next generation owner (commonly they are family business), losing market to modern huge factory, or lack of ingredient supplies.

I wish i can taste my own soy sauce later, and preserving cultural heritage? :raz:

 

I will update my progress. Wish me luck.

 

Thanks.

My soy cake on 3rd day. i think Indonesia has the right climate / humidity for growing mold :raz: white powder is all purposed wheat flour, to prevent soycake stick on the bamboo.

Got error in first trial, it supposed to steam / cook first then blend, but i accidentaly blend first, then after half way, i realized that i haven't cook it yet. LOL. i boiled it, and have an extra pot of soy milk :laugh:

 

well, i'll soak some soy again tonight, making new one, with the right method.

Second batch, 3rd day.

the black mold still dominant, and white mold only seen on the top of the soy cake.

i sprayed  directly with water sprayer to keep them moist. top it with some newspaper to make  dark environment.

 

PS: the black mold maybe Mucor racemosus Fresenius, which involved in Tou Shi fermentation in Sechuan.

Wow, so EIGHT years after first posting on this thread, I finally decided to take the leap and make my own soy sauce. I used a mixture of organic whole wheat flour and white flour.  Combined with the really warm weather around here the mold has taken hold very quickly despite being only two or three days. Little bits of black, yellow and green mold, but mostly white mold, both the fluffy and spotty kind.  It already is very aromatic, very hard to describe...kind of bready and kind of "meaty". I guess all the baking and fermenting in my house has made it teeming with awesome cultures. I'll take a picture of the molded loaf slices after in a few days.  

 

After much research I've decided on a brine concentration of 18%. I think I will skip the drying process and just put the bean loaves directly into the brine

Hello Takadi, nice to meet you. My question to you: is the black mold really safe? Not poisonous?

My soycake contain white and black mold only. I'll take a picture soon :)

 

Soycakes day 5:

Even mold grows on the back of bamboo tray :laugh:

Are those soy cakes ready to put in brine? or need more days?

Thanks, Takadi.

UPDATE:

 

Rest in peace soycake number 2. The wold is successful but i found a lot of maggots.  :shock: Discard right away! *sigh*

I suspect small flies around the bamboo tray.

Oh no!  Dang.  

 

Will you try again?  Hopefully takadi will come back and be able to answer your mold questions.

Hi Dan, I can not speak about mold species from an educated position. Other than brine strength I am taking a completely unscientific "artisan" approach to this. From what I've read, the goal is to destroy the microbes with the salt but not the enzymes that act on the proteins and sugars of the wheat and soy. So in theory the "bad" microbes that produce toxins will not survive past a certain brine percentage.

 

From the many many blogs I've scoured on the internet where people are taking on this home-made soy sauce venture, almost all of them have bits of black mold here and there but none of them have the black mold dominating. There are black colored koji molds but I am unsure if the ones in your culture are of the koji strain. Most koji i've seen is white or yellowish. I suspect maybe your molding environment is too moist, which is also probably why there were maggots. I simply covered my soy loaves with a single layer of wetted paper towels, one or two layers of newspaper, and some single sheets of cling wrap scattered on top.

Shelby: yes i am! still soaking 1/2 Kg of soya bean again :biggrin:

 

Takadi: i think so, the weather now is quite hot and humid here in Indonesia. and i think maggots comes from fly eggs which laid down on the soy cake, maybe next time i'll put some "barrier" to prevent flies coming.

 

I have an idea using Korean method, which mean make "Meju". From pure soya bean, no other rice or grain like Chinese or Japanese method.

I watched on Youtube, here:

looks easier hehehe..

 

Thanks for your reply.

Here are my molded loaves! I couldn't wait any longer...I think they are ready for the brine don't you?

I think I finally know what that "meaty" smell is. It smells like natto and a little like blue cheese and tempeh. There's also a yeasty smell I recognize from making rice wine. Lots of funky stuff going on.

 

As was in Sambucken's case, you could definitely feel a heat emmanating off of it

 

I think I will be continuing to use sight and smell as my main metrics for this experiment.  To me a "fishy" smell or rotten/unpleasant smell will be a sign of failure as well as any sort of weird pest or microbial infestation. That will mean to me that the brine strength was too weak and/or the wrong microbial strains have taken hold.

 

Fortunately I will be the only test guinea pig in the taste tests so my friends and family can rest easy

Thanks for the link Takadi.

My mom just told me about her childhood experience, my great grandmother made her own taucho (indonesian taushi?) Using ungrounded soy bean, steamed, combine with rice flour (not wheat, wheat doesn't grow in indonesia), add tempe yeast, and fermented in a ceramic jar. And she said that the mold should be white and yellowish. And now i persuade her to make an experiment on her own hahaha. She bought tempe, slice it thinly, put in an airy place, then when moldy she dried it under direct sunlight on a baking tray. I'll post the photo later :)

more update:

 

i dry the meju in direct sunlight at noon, and move it to dark and warm room at night, the result is good, when i move them in the morning, heat generated under the basket, feel warm.

 

black, white, and pinkish / orange mold. no maggots :raz: .

Oh god I think I made a mistake. I forgot to account for the weight of the actual soybeans and flour when calculating the salt percentage. 18 percent is supposed to be the *final* salt percentage of the soy sauce, not the initial brine. The soy sauce doesn't smell terrible but it's starting to form a pellicle on top which isn't a good sign.  I'll start over but I'll add more salt to this batch and let it continue to ferment in another batch to see where it goes.

I am in! I have read and reread  … I have 2 Korean friends who  make soy sauce and miso but they buy the pre made cakes at the market ..when I mentioned that i was going to try to make the cakes I got an automatic revulsion over it and they directed me again to the market 

 

so I am going to read research and follow you folks …along  with the advice of my friends who fight over how they do it anyway iso this should be fun and they both make incredible sauce and miso ..

 

when I get a break and feel confident I am going to  make one with the home made cakes I will make one with the store bought cakes as well and see how different this is 

 

I absolutely ADORE home made Korean chunky dark miso it is the best thing I have ever eaten miso wise and I have so much trouble finding it that if takes making my own soy sauce to get it ? that is what I am doing 

 

please add any and all info you may think interesting because even if not posting ..many of us will be reading for sure 

thanks so much! I hope to reciprocate someday when I get to making it 

 

I live in the Puget Sound grow lights and a fan if we do not have another summer like we just had!

      I just got a copy of Grace Young's "Stir-Frying to the Sky's Edge"—I enjoyed cooking from "Breath of a Wok" and wanted to continue on that path. Does anyone else have this book? Have you cooked anything from it?

      Here was dinner tonight:

      Spicy Dry-Fried Beef (p. 70)

      I undercooked the beef just a bit due to a waning propane supply (I use an outdoor propane-powered wok burner), but there's nothing to complain about here. It's a relatively mild dish that lets the flavors of the ingredients (and the wok) speak. Overall I liked it, at will probably make it again (hopefully with a full tank of gas).

      We are all used to unami now. Maybe it's time to consider gan. Particularly found in teas, but also in other foods. An interesting article from a great magazine.

      I’m an idiot. It’s official.
       
      A couple of weeks back, on another thread, the subject of celtuce and its leafing tops came up (somewhat off-topic). Someone said that the tops are difficult to find in Asian markets and I replied that I also find the tops difficult to find here in China. Nonsense. They are very easy to find. They just go under a completely different name from the stems – something which had slipped my very slippery mind.
       
      So, here on-topic is some celtuce space.
       
      First, for those who don’t know what celtuce is, let me say it is a variety of lettuce which looks nothing like a lettuce. It is very popular in southern mainland China and Taiwan. It is also known in English as stem lettuce, celery lettuce, asparagus lettuce, or Chinese lettuce. In Chinese it is 莴笋 wō sǔn or 莴苣 wō jù, although the latter can simply mean lettuce of any variety.

      Lactuca sativa var. asparagina is 'celtuce' for the technically minded.
       

       
      Those in the picture are about 40 cm (15.7 inches) long and have a maximum diameter of 5 cm (2 inches). The stems are usually peeled, sliced and used in various stir fries, although they can also be braised, roasted etc. The taste is somewhere between lettuce and celery, hence the name. The texture is more like the latter.
       
      The leafing tops are, as I said, sold separately and under a completely different name. They are 油麦菜 yóu mài cài.
       

       
      These taste similar to Romaine lettuce and can be eaten raw in salads. In Chinese cuisine,  they are usually briefly stir fried with garlic until they wilt and served as a green vegetable – sometimes with oyster sauce.
       
      If you can find either the stems or leaves in your Asian market, I strongly recommend giving them a try.

      “… and so it begins!”
       
      Welcome to “Tales from the Fragrant Harbour”!
      In the next couple of days I am hoping to take you to a little excursion to Hong Kong to explore the local food and food culture as well as maybe a little bit more about my personal culinary background. I hope I can give you a good impression of what life is like on this side of the globe and am looking very forward to answering questions, engaging in spirited discussions and just can share a bit of my everyday life with you. Before starting with the regular revealing shots of my fridge’s content and some more information on myself, I’d like to start this blog and a slightly different place.
      For today's night, I ‘d like to report back from Chiba city, close to Tokyo, Japan. It’s my last day of a three day business trip and it’s a special day here in Japan: “Doyou no ushi no hi”. The “midsummer day of the ox”, which is actually one of the earlier (successful) attempts of a clever marketing stunt.  As sales of the traditional winter dish “Unagi” (grilled eel with sweet soy sauce) plummeted in summer, a clever merchant took advantage of the folk tale that food items starting with the letter “U” (like ume = sour plum and uri = gourd) dispel the summer heat, so he introduced “Unagi” as a new dish best enjoyed on this day. It was successful, and even in the supermarkets the sell Unagi-Don and related foods. Of course, I could not resist to take advantage and requested tonight dinner featuring eel. Thnaks to our kind production plant colleagues, I had what I was craving …
      (of course the rest of the food was not half as bad)

      Todays suggestion: Unagi (grilled eel) and the fitting Sake !
       

      For starters: Seeweed (upper left), raw baby mackerel with ginger (upper right) and sea snails. I did not care for the algae, but the little fishes were very tasty.
       

      Sahimi: Sea bream, Tuna and clam ...
       

      Tempura: Shrimp, Okra, Cod and Mioga (young pickled ginger sprouts).
       

      Shioyaki Ayu: salt-grilled river fish. I like this one a lot. I particularly enjoy the fixed shape mimicking the swimming motion. The best was the tail fin
       

      Wagyu: "nuff said ...
       

      Gourd. With a kind of jellied Oden stock. Nice !
       

      Unagi with Sansho (mountain pepper)
       

      So, so good. Rich and fat and sweet and smoky. I could eat a looooot of that ...
       

      Chawan Mushi:steamed egg custard. A bit overcooked. My Japanese hosts very surprised when I told them that I find it to be cooked at to high temperatures (causing the custard to loose it's silkiness), but they agreed.
       

      Part of the experience was of course the Sake. I enjoyed it a lot but whether this is the one to augment the taste of the Unagi I could not tell ...
       

      More Unagi (hey it's only twice per year) ...
       

      Miso soup with clams ...
       

      Tiramisu.
       

      Outside view of the restaurant. Very casual!
      On the way home I enjoyed a local IPA. Craft beer is a big thing in Japan at the moment (as probably anywhere else in the world), so at 29 oC in front of the train station I had this. Very fruity …

       
      When I came back to the hotel, the turn down service had made my bed and placed a little Origami crane on my pillow. You just have to love this attention to detail.

      I make this a lot. Traditionally served with dosa, but great with all kinds of Indian food, even just scooped up with bread or pappads for a snack. Although it's slightly different every time, depending on the tomatoes and chillies used, plus the strength of the tamarind, it's easy, quick to make and always delicious.
       
      In a blender - half a medium red onion chopped, 7 dried red chillies broken up a bit, 2 ripe tomatoes chopped, 1 tsp of sea salt, 3 tsp tamarind paste.

       
      Whizz until purée like about 2 minutes.

       
      In a sauté pan over medium heat add 60 ml sesame oil (gingelly), when it's hot but not smoking add 1 tsp black mustard seeds.   

       
      Quickly cover the pan to prevent escape and sizzle for a minute.

       
      Add 1 tsp of urad dal (black lentils, skinned and split they are light grey).

       
      Fry until golden, another minute or so.

       
      Throw in about 20 curry leaves. These splatter so cover the pan again. 

       
      Lower the heat and add the  blender contents.

       
      Simmer, stirring frequently for about 10 minutes, until you get a runny jam consistency.
       
      Ta da !
