Homemade Soy Milk Thermomix

Published , Last Updated

Homemade soy milk is simple to make even if you don’t own a Thermomix. But of course, Thermomix makes everything easier!

Homemade soy milk is simple to make in the Thermomix. It's a plant-based milk that's naturally high in complete proteins & vegan friendly.

There are so many reasons why people decide they need a Thermomix in their life. One of the more common reasons is they want to start making healthier food for their family. Healthy food means no pre-packaged sauces or packet mix products and knowing what’s in the food you eat.

Soy milk is a plant-based milk that is naturally high in complete protein. It’s suitable for those following a vegan diet and those that are lactose intolerant and dairy free.

In addition to being a healthy beverage, homemade soy milk can also be used as a milk substitute in cooking and baking.

Why Make your own Soy Milk

Soy milk is readily available in the supermarket, so why should you make your own?

Choosing Organic Non GMO Milk

Did you know most soy milk isn’t organic? Also, most beans used in the production of soy milk are from GMO crops! No… nor did I until a client mentioned it to me. It’s easy to find organic, non-GMO soybeans, but quite often organic soy milk is unavailable in the supermarket. So if organic eating is important to you, it’s good to be able to make your own soy milk.

What is added to your Soy Milk?

Commercially prepared soy milk can contain more than just soybeans and water. Some varieties of milk use preservatives, sugar, flavouring, and fillers, along with added vitamins and minerals to help boost the nutritional value of the product that may have been destroyed by heat treatments.

So this recipe makes soy milk using organic, non-GMO, Australian-grown soybeans and water. Just two ingredients and a simple process.

Keeping Costs Down

To keep the cost of your organic soy milk down, buy your soybeans in bulk. This is so cost-effective! I cup of dried soy means (180g) makes one litre of soy milk. That’s very cost-effective. 

Why Soak Soybeans?

The soybeans need to be pre-soaked prior to commencing the recipe. I recommend soaking them overnight or for at least 8 hours. This serves 3 main purposes;

  1. Soybeans are high in phytic acid which can reduce the body’s absorption of minerals such as calcium, magnesium, iron, and zinc. Soaking reduces the levels of phytic acid in the beans and improves mineral uptake.
  2. Dried soybeans are very hard and take a long time to soften if not soaked prior to processing or cooking. Soaking reduces cooking time.
  3. The soaked bean’s outer membrane is broken down which releases the oligosaccharides (type of carbohydrate) into the water. This makes soybeans more digestible and less likely to cause gas or bloating.

What Does Homemade Soy Milk Taste Like?

You may find that homemade soy milk tastes a little different from commercial soy milk. There is a number of reasons for this, firstly if you take a look at the ingredient list of your regular soy milk you will notice a few additional ingredients. Most commercial varieties contain oil, salt, sweetener, and even flavours. So you may find your homemade soy milk has a little bit stronger flavour than you are used to.

Adjusting Flavour & Sweetness

Use this as your base recipe, but feel free to experiment with it.

  1. You can make “skim soy milk” by adding extra water. This will give you thinner milk with fewer calories.
  2. Add a natural sweetener such as blending a Medjool date or adding some honey or maple syrup.
  3. Add a pandan leaf to the boiling process to infuse a subtle natural flavour.
  4. Place a teaspoon of vanilla in the cooled milk.

How to Use Soy Milk

Keep the soy milk refrigerated until needed. Soy milk can be used in place of regular dairy milk. Serve the mylk on your homemade Granola for a healthy breakfast or use smoothies like this delicious Scorched Peanut Bar Smoothie.

Step By Step Soy Milk

Squeeze the milk from the Nut Milk Bag
  1. Blend the soybeans with water, as per the recipe, and pour the liquid into a nut milk bag.
  2. Squeeze all the liquid (milk) out of the bag.
  3. Wash the TM Bowl and proceed with heating the milk as per the recipe.
