Although this product is widespread, seen in almost any supermarket, sari sari store or wet market making your own soy sauce at home can also be a sideline income specially if you can make a better one. But for starters, you can start a simple procedure like the one I got below before you can experiment on your own. Just remember, even a simple product like these and having so many competition can be overcome by creativity. Again remember the saying ” A journey of a thousand miles begins with a single step”.

Mix soybeans and flour thoroughly. Sprinkle rice bran with molds (3 days old) over the mixture and mix well. Spread mixture 1-2 inches thick in a tray. Cover with clean cloth or paper and allow the molds to grow. Stir occasionally.

After 3-4 days, transfer the mixture to a container with salt solution. Cover the container with paper or cloth and shake well. Set aside for 1 month. Stir once in a while.
