Like so many things, soy milk can be made quickly and easily in the thermomix. Yes, a little forethought is required as the soy beans need to be soaked overnight but very little effort is otherwise required.
In terms of cost, I priced 1 litre of organic soy milk at $3.95. At the same store, organic soy beans were $4.95 for a 500g bag. I used 370g of beans to yield 1.75 litres of soy milk. So the cost per litre is $2.09. Quite a saving!
Because I made a large batch, I needed to dirty a stock pot to combine the puree with extra water before straining. This was using 370g of beans and 2 litres of water. To reduce the amount of dishes, I have halved the amounts. If you use a lot of soy milk and would prefer to make the larger batch, simply puree the beans starting with 500ml of water, adding another 500ml as you go, then empty into a stockpot stir in another litre, bring to boil and strain as per the recipe below.
Thermomix Soy Milk
1 cup or 185g organic soy beans, soaked over night and drained
1 litre water
1. Place beans and water in thermomix and puree on speed 9 until thermomix stops dramatic shaking, about 30 – 45 seconds.
2. Cook at 100 degrees for approximately 8 minutes on speed 2, or until temperature reaches 100 degrees.
3. Line a large colander with a double thickness of cheesecloth or muslin and place over a large pot. Pour contents of thermomix into colander.
4. Twist top of cheesecloth closed and press out soy milk with a wooden spoon until no liquid remains.
Thank you for posting this recipe. My LO has dairy and egg intolerances, so soy milk is now a staple in our house. I just purchased 5kg of organic soyabeans, and will be soaking some for our first batch of soy milk tomorrow. Very excited, especially just looking at the savings!
Good luck! Happy to help, it certainly is a much cheaper way of getting a premium quality product!
