How much tempeh can i eat daily?

There's is no minimum or maximum amount. We only advice that tempeh is part of a well balanced diet. The FDA recommends consuming daily about 25 g of soy proteins, or 2 to 3 oz Tempeh.

What soybean varieties are suitable for the production of tempeh?

The only beans in our opinion to create the taste of original Indonesian Tempeh are Yellow Soy Beans, although there are no specific varieties which could be used for the production of tempeh. To obtain the "fresh nutty taste" of Tempeh only the big yellow Soy Bean should be used, if you want to use instead of Soya Bean, an other kind of bean, this is no problem in the process, it only gives a different taste then Indonesian style tempeh.

Can I eat raw tempeh?

Fresh tempeh is eaten cooked, either fried, steamed or boiled.

How do I know that my tempeh is still good?

In fresh tempeh the soybeans should be bound together into a tight cakes with no mold growing other than the white tempeh culture. Small black spots may occasionally appear. These spots do not necessarily indicate spoilage, but are part of the tempeh culture's life cycle.
The texture should not be slimy and the aroma should be mushroom-like (or nutty yeast-like). A every slight smell of ammonia is normal. This smell will increase if you incubate the tempeh too long, indicating that the proteins have been broken down too much.

My batch of homemade tempeh is spoiled, can I prevent this in the future?

There could be many reasons but the most important one is the incubation of moist beans. Moist is the number 1 reason which will spoil your batch of Tempeh. Then other organisms will grow and compete with the tempeh mold. This will result in a slimy texture and a strong smell of ammonia.

Other reasons could be:
- using old or inactive starter(starter should be kept in a dark, cold and dry   place)
- working conditions were not hygienisch
- too high incubation temperature which kills the mold (temperature should be 86 F).

Molds can produce toxins, how safe is tempeh?

The molds (Rhizopus) used for the production of tempeh are eatable and don't produce any known toxins.

My tempeh has some black spots, can I still use this ?

The formation of black spores, especially around the air holes, where there's a lot of oxygen, the molds could produce some black spores. This tempeh is still eatable, and is normal. To Indonesian people black spores are a sign of a good tempeh(maker).
Depending on the Rhizopus strain could will happen sometimes after 2-3 days of incubation. To produce white tempeh, carefully follow our instructions,if the temperature is too hight or incubation time too long this could happen, our spores strain produces perfect tempeh, if directions are followed.

What is Black Oncom?

Tempeh - Soybean Cake

Tempeh is made by a natural culturing and controlled process that binds particles into a cake form. It originated in , where it is most popular, although it is common in other parts of as well. It is especially popular in Indonesia, where it is a source of protein. Like tahu or toufu, tempeh is made from soybeans, but tempeh is a whole soybean product with different characteristics and textural qualities.

How to make incubators:

There are many expensive incubators on the market but it is very easy to make your own tempeh incubator. All you need is an old refrigerator (which are easy to find ) The heat produced by the lamp should be controlled with a dimmer. An old refrigerator is the ideal incubator: it's isolated, easy to clean and it contains racks for stacking tempeh slabs

Installing the lamp

The lamp fixture should be on the bottom at one side of the ref. for random heating. Most refrigerators have a hole at the back (for the cable, lines or to let the condense out) which you can use to pull out the electric cord, otherwise you will have to drill a hole.

Control the temperature

It's important to check the temperature during incubation because tempeh , especially at the end of the fermentation process, will produce its own heat. The temperature of the incubator should be between 85-89F. You can controlling this by adjusting the dimmer button. Remember that the most import mistake for spoiled tempeh is too high temperature, too much moisture, or not working clean. If you want to invest a bit more you can install a digital thermostat and a ventilator to control the temperature and the environment.

Cheap solutions:

Cardboard box

Use a cardboard of about 3' x 6' x 3' ft or larger. Isolate the outside of the box with polystyrene foam. Put the carton in the upright position and place a light and dimmer at the bottom, Create rack on the inside for the tempeh Electric oven Modern electric ovens not working well, do not use them, just use the oven as warm place, and put a hot water bath inside to keep the temp around 85 - 90 F. No incubator Of course you don't need an incubator if you live in a warm place where the temperature is ideal for growing tempeh. Tempeh originated from Indonesia with a warm climate the whole year round is solely made by just putting the tempeh outside, the wind and the temp. will do the rest.

How to make Tempeh in bananaleaf?

Instead of using a plastick ziplock, use a bananaleaf, the principe is the same:

Simple clean your bananaleaf, wipe it dry, punch at every 1/2 inch of the leaf a hole. Spread the soybeans evenly on the leaf and folt the leave up. ( like a spring roll ), put some toothpicks to hold it all together, and transfer to your incubator, and your done.
