How to Make Yoghurt In a Thermos Flask?

If you are a fan of yoghurt, you may have wondered at some point in your life whether it is possible to actually make your own from home. This is because yoghurt can be expensive. I mean, let’s face it! If you get into the habit of buying it every time you have a craving, you’d probably go broke before you know it. Luckily, there’s a way you could make yourself lots of yoghurt right from home using easily available equipment. The thermos flask is actually very good at making homemade yoghurt and in this article, we are going to show you how to go about it. If you need to buy one of these first, check out our thermos flask reviews.

What you need?

The following are the ingredients you will need to make yoghurt using a thermos flask from home:

  • UHT or fresh milk
  • Powdered milk
  • Natural yoghurt with live cultures
  • Thermos flask

Step 1:

Dissolve the powdered milk in the fresh milk in a pan and heat the mixture up to 820 C. Once this temperature is achieved, allow the mixture to cool for about 10 minutes to 460 C. Just make sure the temperature doesn’t drop below this point.

Step 2:

Sterilize the thermos flask by filling it with hot water and covering it with the lid. This will also help to preheat the thermos flask thus creating a conducive environment for the milk.

Step 3:

Now add the yoghurt into the milky mixture while whisking it to ensure they mix completely. Once this is done, remove the hot water from the flask to create room for the mixture you’ve just created (milky mixture and yoghurt).

Step 4:

Now cover the thermos flask with its lid and wrap it with a piece of cloth or towel. This will ensure that it stays warm through the night. Make sure the position is far away from movement because the thermos flask should not be knocked at all. Depending on the prevailing temperatures, it could take between 7 and 16 hours for the yoghurt to be ready. Again, it comes down to personal preferences because people have varying tastes when it comes to the consistency of the yoghurt. Once you are satisfied with the consistency of the yoghurt, you can take it out of the thermos flask and store it in the fridge awaiting consumption.

Factors to consider

As you can see, the preparation process is quite simple and straightforward. As long as you have all the ingredients in place, making yoghurt at home can be the simplest and most enjoyable task you could ever engage in.

Now, the size of the flask should match the ingredients. You do not want to make your yoghurt only to realize later that you used more milk than necessary or more yoghurt cultures. To avoid this, make sure the capacity of the thermos flask is proportional with the amount of each ingredient that you are going to use. Another thing to consider is the temperature of the milk and the thermos flask. When you are heating the milk, try as much as possible to avoid overheating or under-heating. This will help a lot in enhancing the consistency of the final product. The temperature of the thermos is also very important. Remember that the thermos flask is the one responsible for creating the conducive environment to form yoghurt. If you get this wrong, the chances are that you will get a spoilt product at the end of it all.

In summation, making yoghurt at home is not a difficult experience as long as you have the right ingredients and you pay attention to the details.
