About Tempeh

Tempeh is a fermented product from Indonesia made from soybeans and fungi. During the fermentation, the fungus feeds on the soybeans and grows in the space around them, binding them together. This processs breaks down the molecules and this pre-digestion allows us to absorb many more nutrients from the soybeans. That makes tempeh as rich in protein and iron as meat. It is also higher in fibre and calcium while being lower in saturated fat and salt. The taste of tempeh evokes aromas of mushrooms, nuts and yeast, and its texture is firm, chunky and “meaty”. Extremely delicious!

About the Domingo necklace

The Domingo Necklace is a poetic invitation to anyone to start fermenting tempeh without any other device than your body.

How to make tempeh with the Domingo Necklace

prepare the soybeans

Measure the amount of beans by placing the moon-shaped measuring tool in the petri dish and filling the remaining space with soybeans.
Soak the prepared beans in a small container of water overnight.
Boil the soybeans in water with a drop of vinegar for 25 minutes.
Strain the beans and dry them with a clean cloth.
Put them in a bowl and sprinkle with a quarter of the tempeh starter powder.
Mix well and place them in your petri dish (removing the moon-shaped measuring tool first).
