One of those lunch time conversations with the colleagues turned into how much sugar was being put into soy milk drinks that you get from the vendors or boxes... So, when I stumbled across the recipe to make it at home (in a new blender's manual of all places), was eager to try it. Have to say, it def was a little time consuming than pouring it from the box, but I guess you could just make a big batch and store them in bottles in the fridge (note: for up to three days).
Homemade Soy Milk
1/2 cup Dried white soy beans
2 1/2 cups Water + 3 cups water
Organic brown sugar - to taste
Fine sieve or cheese cloth
1. Soak soy beans in a bowl of water (make sure the beans are covered with water) for at least four hours or better yet, overnight.
2. Pick out any discoloured or not-expanded beans, rinse and drain.
3. In a food processor, put in soy beans and water (roughly the ratio is 1/2 cup beans : 2 1/2 cup water). Puree until smooth and milky.
4. Transfer the mixture to a large pan and add additional 3 cups water. Bring to a boil, constantly stirring and skimming off the foam. Turn heat to low and simmer.
5. After about 15 - 20 mins (you will start getting the "sweet" soy milk smell), take off heat and strain through sieve / cheese cloth.
6. Add sugar to taste.
