I'm going to mark this as a failed first attempt. After deciding the mold had plenty of time to do it's conversion on the soy beans and brought them out to the sun to dry a bit. After a few hours of Florida sun it looked like rain so I brought the trays in. I then decided to bake in a low oven to continue the drying process. This was a BAD idea. the resulting smell in the house was enough to make me second guess my actions. When I retrieved the trays from the oven I cut into the paste to see if it's dried much at all and it turns out only the surface was getting dry. I figure at this point the only real investment wasted is time, a few dollars in soy beans and wheat flour since I haven't added the rest of the ingredients yet. Here are a few things I would change for a second try;
-Make a smaller batch, 1 pound of dry beans max maybe only half that!
-Puree to a finer paste.
-Mix Koji Kin throughout paste rather than dust the surface to ensure proper distribution of the good mold (the paste shrinks a bit as it dries).
-Make thinner patties.
-Place on a wire rack to improve air circulation.
-Do not use oven for drying!
Now comes the fun part of disposal since the garbage truck won't be by for a few more days. I have placed it in several layers of bags and a good dousing of baking soda. It may be time to fill up the gas tank just to dump it in someone else trash.

Homemade Soy Sauce-Part One
I've been thinking about soy sauce lately which got me thinking about how it's made. After a ton of online research I think I was able to gather enough information from numerous sites to piece together the puzzle. Being a homebrewer I was thinking in terms of using the appropriate strains of yeast, mold, and bacteria to get the job done right (and safely).
It seems as though there are several attitudes ranging from the straight forward simple to the lets throw the dice and hope it works method. As well as papers on large scale manufacture of soy sauce. I wanted to learn how to do it in an old school take your time and do it right mentality.
The first thing to do is source your ingredients. This consist of the following (with approximate cost);
-organic dried soy beans (local health food store) $6 for 5 pounds
-good quality whole wheat flour, I used King Arthur's Whole White Wheat (grocery store) &4
-Koji Kin mold spores in the form of a Homebrew Sake Kit (local homebrew supply) $8
-yeast, I am using an ale yeast SafAle US-05 (local homebrew supply) $3
-lactobacillus (local homebrew supply) $10
-sea salt (grocery store) $2
The next stage is to soak your beans in water for about 12 hours changing out the water at least once. When this is done change the water one last time and cook the living hell out of it until the soy beans break apart into a mealy texture between your fingers. This took about 3 hours for my over sized batch. Then let the beans cool in the cooking liquor then strain and begin to make a mash out of them achieving the smoothest consistency possible. Mine did not turn out very smooth since I started out with about 5 pounds of dried beans which I've since learned is way too much to mess with at home. At this point it's time to incorporate the flour I used 2 1/2 pounds of flour to 5 pounds of dried beans. This will dry out the mixture a fair bit and you can make patties out of it to let the fermentation begin. Once the patties are made (mine ended up being the size of a half sheet pan) it's time to inoculate with our safe mold spores (the same ones used to make sake) I took a few grams of the mold spores and mixed with white flour and then sifted over every inch of my soy paste then moved them out of the way and covered with a damp paper towel to let the transformation begin. It only took about a day to see the signs of the Koji Kin working on the soy mix with the fine white hairs as instructed in the sake making kit that would be present. This is a very positive sign that we're on the right path. I think in the next day or two I will dry this mix out the rest of the way and begin the second fermentation with the lactobacillus and yeast. Sine my yeast is not a salt tolerant variety I will minimize the salt for the first few days to let the yeast do it;s thing on some of the converted sugars from the Koji Kin.
By introducing the lactobacillus this will become a very long process I believe to turn into a finished product. It's my goal to split this into a few small batches to try different aging methods like different woods and just on it's own.

Here you can see my paste isn't very paste like but the Koji Kin is doing it majic on the soy beans.
