Wash and Soak soya beans for 1hour

After an hour wash,sieve and grind until well ground

Add more water to the paste and sieve in a big pot as we are using the milk color extract,rinse until the water comes out clear

Place the pot on fire and allow to boil...when it boils add in the sour water gradually you will notice it to foam clots add more sour water until the water become light in yellow

Sieve it using a clean kitchen cloth(also known dankwalin tata) always use for sieving then you tie it up not too hard
