I've been making tempeh lately. Its better for me and tastes so good. Dinner tonight was poached veggies, very simple Japanese style. The tempeh is pan fried with a little chipolte seasoning sprinkled on top.
For those who do not know, tempeh is an Indonesian fermented soy cake. It is mycelium mold that forms around the soybeans. You have to inoculate it with powdered tempeh starter, similar to how you have to use probiotics to make yogurt. The fermentation starter is called Rhizopus oligosporus and it likes a temperature of about 85-88 degrees Fahrenheit to mimic the natural ambient temperature, as in its native country it sits around and uses the natural heat of the day to incubate. Yes, inoculate and incubate, the food as of late. My husband is really freaked out about my recent food adventure, to say the least.
Why do all this weirdness? Firstly, its better than tofu, which is really processed. Secondly, it can be controlled to be non-GMO and all natural, no emulsifiers or thickeners they use in tofu production. Thirdly, it tastes a thousand times better than tofu. Its a mild, mushroomy and meaty flavor that is very wonderful. Its really is amazing. I cant get over how good it is and how proud I am to be able to make this from scratch.

I like the smaller Korean soybeans (they sprout them) and get them for a dollar a pound at an Asian grocery store; the four pound bags cost me $3.99 plus tax. It makes 4 batches. The powdered tempeh starter was purchased from ebay for $6 USD; the vendor sent it in a regular letter, as it was a small 20 gram bag. Ive transferred it to a brown bottle to keep it fresh. If you keep it in the freezer it keeps it fresh too though, maybe I didn't need the bottle after all. Other than a saucepan, a measuring cup, teaspoon and tablespoon, a little thermometer (ambient, wall type. Costs $1 at walmart) and a couple quart sized baggies, its relatively low tech and easy once you get the hang of it.
Boil the beans 15 mins first. You want to loosen the hulls this way. I used to 12-24 hour soak method first, but this method works so much faster.
2 cups of beans dried. This makes two 12 oz bags of finished product.
Cool off those beans with some cold water. Youre gonna stick your hand in there and start squeezing and rubbing the beans to get the hulls off. The hulls are translucent.
The hulls start to float. You can skim them off by swishing the beans around and then using water to get them to rise and then drain the water off...they come right off. You have to do this several times; keep squeezing and rubbing them, then agitate them to get the hulls to float and then skim the water off.
Then, fill more water in the pot, like a couple inches above the line of the beans. Cook them all the way through, or about 45 more minutes. They should be soft enough to where you can eat them. Not al dente...you want them soft enough to eat normally.
Towel dry the beans. You want to remove the moisture. You can also use a hair dryer too. I like to use two towels. Lay them on one towel and dry, then transfer to a drier towel and do it again. They should cool off to below 85 degrees F or more.
While its drying off, you can poke holes in quart sized bags. I use two at a time. A bigger skewer is a nice size hole. it needs to be a little bigger to get good air circulation.
So this is inoculation time. Use two tablespoons of vinegar to lower the Ph...mix it well. You can use fresh lemon too. One teaspoon or (3-5 g) of tempeh starter gets mixed in well. Sprinkle a little and mix...sprinkle and mix...make sure it gets evenly distributed.
Ideal temperature is 86-88 degrees Fahrenheit. Too extreme in any direction will not yield a firm cake; it will be mushy, spoiled and smells funny if its too hot or cold. I have drawn sharpie marks of the zone it needs to stay in. It does not develop faster the hotter it is.
The trickiest part of this venture is finding a good spot that has a stable ideal temperature for at least 12-16 hours. I use the oven light to warm it up, but it does get too hot after 6 hours so I use a rolled up towel to crack the door open to get good ventilation.
It will look like nothing is happening for a long time and then BAM it starts to spore and develop a whitish haze, which will then keep developing and at this stage it actually even produces its own heat while fermenting.
You have to make sure the temps can be lowered. I take it out of the oven at this point and use a shoe box on the counter top; the holes on the top of the Nike shoe box ventilates the internal heat from fermentation just the right amount. Again, you have to play around with the areas of your house and the incubation area.
It looks like this after 24-30 hours. You will see tiny dark spots where you poked holes in the bags. It feels dense and solid and not movable at all. Put in the fridge to stop the fermentation process.
I slice it and place in an airtight container, ready to fry, bake, marinade, or whatever process to flavor and finish it. It is really so amazing and tastes so so so good!!!
