This week in my Facebook group, I promised my dear followers that I would share my method of making homemade yogurt using my TM6. A few years back, I wrote a post about making yoghurt in a dedicated yoghurt maker. This time I’m sharing my method by utilizing the fantastic Fermentation mode in the TM6 Thermomix. I’m thrilled to introduce another simple and fast solution for homemade yoghurt. So, are you ready to begin?

If you’re new here, you may not know I’ve been making yogurt for about 30 years, which started because my son had some rather nasty food allergies growing up. So don’t worry if you don’t have a Thermomix; I’ve written a post before about making yogurt the old-fashioned way with a dedicated yogurt maker. So if it’s a non-Thermomix method that you need, then click here.

Yoghurt in the Thermomix?

However, I’ve fallen head over heels for the ease of my TM6 Thermomix, and I can confidently say that it’s my preferred method for yoghurt creation these days. Why clutter the kitchen with an array of devices when one can do the job marvellously?

So, let’s get down to the details, shall we? If you’ve been part of our community for a while, you know I’m all about simplicity and efficiency in the kitchen, and making yoghurt with the Thermomix is no exception.

Ingredients for yoghurt making

First, we need a yoghurt starter or culture: You can use a portion of fresh pot-set yoghurt straight from your supermarket or even some leftovers from your previous batch of yoghurt-making (make sure it’s not contaminated). Either way, it’s going to work just fine. In my opinion, it’s important to use a plain pot set yoghurt; you’ll find it’s much more reliable, and it’s so easy to turn plain yogurt into an array of different flavours (see below)πŸ‘‡ Look at labels on the pot at the supermarket you see the words “pot set”.

Or you can purchase yoghurt culture. I use this product by Mad Mille from time to time. The reason I use it, is that it just never fails. The product states that it’s shelf stable for around eight months, but if you keep the packs in the freezer, they will last much longer than that. There are five sachets in one pack; I use 1/2 a sachet per 1 litre, then I reuse that made-up yoghurt (back slopping *see below) for my next batch around 5 – 8 times before starting with a new batch from the sachets. Use at least 60g of yoghurt to innoculate your next batch.

Why do I start a new batch, I hear you say?

Yoghurt culture

If you’re using a portion of your homemade yogurt as a starter for the next batch (a process known as “back slopping”), the cultures from the original yoghurt should be able to inoculate the new batch. This is because these bacteria can replicate during the fermentation process.

However, over time, the strength and viability of these cultures can diminish, especially if the conditions are not optimal. Variables such as the temperature during incubation, the freshness of the milk, and the length of fermentation can affect the viability of the cultures.

Generally, it is recommended to use a fresh starter culture after several batches of back slopping to ensure a robust population of bacteria/probiotics. I suggest doing this after about 5-8 batches, but it can vary.

It’s also important to remember that different probiotics can have different growth requirements and abilities to compete with other bacteria present, so if you’re trying to maintain a specific blend of bacteria, you might need to refresh with a new commercial starter occasionally.

What milk do we use for making yoghurt?

Next, we have 1 litre of UHT milk. The choice of milk is entirely up to you. We tend to use A2 UHT milk at home, but you could choose whatever works best for you, whether that’s based on price, taste, or dietary considerations. I’ve had more experience with UHT cow’s milk than anything else, and it doesn’t seem to matter what brand, they all seem to set fine for me. Although the colour can be different, some are white, and others are anywhere between grey and cream.

Of course, you can use fresh milk from the dairy cabinet at the supermarket, but fresh milk requires a few more steps before you can go straight to the fermentation stage. This guided cookidoo recipe will step you through the process of using fresh milk as opposed to UHT.


I use skim milk powder. I know some recipes call for full cream, it’s up to you, but I don’t see the point in adding more fat via this method. You might wonder why we’re using this at all. Well, the milk powder’s role is essentially to thicken our yoghurt, making it luscious and rich.

But here’s a tip, don’t be tempted to keep adding more, thinking it’ll yield a denser yoghurt. Trust me, it won’t. Overdoing it will instead compromise the flavour and texture. If you’re aiming for that ultra-thick Greek yoghurt style, the trick lies in straining your yoghurt post-fermentation.

So, there you have it! With these simple ingredients and our trusty Thermomix, we’re all set to whip up some homemade yoghurt that’s easy, cost-effective, and oh-so-satisfying. Are you ready?

The method

  1. Add yoghurt (culture) either from your last batch, a pot set yoghurt or powder from Mad Millie.
  2. Then I add Up to 100g of skim milk powder (you can use full cream if you wish)
  3. Around Β½ to 1 full cup of UHT milk and give a mix. MC in 10 seconds/speed 4-5 (if you want to add sugar, do it now 40g in a litre is fine for me. Try it and if you need more next time, add)
  4. Add the remainder of the milk and mix again for Mc in 5 seconds/speed 4 – 5
  5. Pour into your mould/s that are sitting in your Varoma.
  6. Rinse out your TM bowl, and then add 250g of water plus 30g of vinegar (or lemon juice).
  7. Pop your Varoma in place and set to ferment. Flick to the Modes screen, then tap on Fermentation. I choose 12 h/70Β°C or use this recipe from cookidoo and start at step 5

Maintain the temperature until the yoghurt has set. Setting can take between 8 – 24 hours, depending on what you’ve used as your milk and starter. I find different milk types take different lengths of time to set, so don’t worry if yours is taking longer, just set it for more time.   I also find that the best practice is to find a milk and culture you like and then stick with it. Once you’ve got a routine, you’ll be able to reproduce it the same way every time and focus on flavourings.

Another factor to consider is taste. If you prefer a more robust flavour in your yoghurt, leave it to incubate for a longer period. However, if you’re satisfied with the current taste, refrigerate it immediately after it has been set. The yoghurt will thicken a little further in the fridge.

How to achieve a thicker yoghurt?

Add more milk powder

Add up to 100 g of skim milk powder to the milk at the stage you add your culture (step 2 in my method above). I’ve tried adding more, and trust me; the word slime comes to mind if you overdo it. 🀒πŸ€ͺ

Remove the whey

Drain the yoghurt after it has cooled in the fridge. The longer you drain it, the thicker the yoghurt will be. The best practice is to set a straining bag over a colander in the fridge. The usual amount to be drained off is between 250 and 500ml of whey from a litre of milk.

During the cheese-making process, the liquid that separates from milk is slightly acidic and can be used instead of buttermilk in recipes. The whey removed from yoghurt can also be used in the same way. Mixing equal parts milk and whey is effective. If you have extra whey, you can freeze it for later use. Alternatively, you can use fresh whey to water your plants or give it to your dogs as a treat, but be cautious not to give them too much.

Flavour Ideas

I know you want sweet vanilla yoghurt, right?

Well, first, it only takes half to one teaspoon of jam added to a single serving of yoghurt to turn it into a sweet treat. I like to make my own jam and add vanilla to it as I’m making it, so there you have the best of both worlds, sweet fruity vanilla jam.

Shhhh, Don’t tell anyone, but I’ve also been known to purchase a jar of Bonne Maman jam (I like strawberry but it comes in so many flavours). Your options for toppings are only limited by your imagination. Consider options like honey, maple syrup, fruit, jam, crumble, granola, or whatever you desire. When I crave something sweet, I portion out the yogurt into single-serve bowls and stir in a teaspoon of jam. Sometimes I even sprinkle granola and chopped fresh fruit on top. This makes for an easy dessert for those who need a sweet treat after dinner.

So go on, make some homemade yoghurt this weekend πŸ™‚

    1. Hi Nic, do you have a TM6 Thermomix? If you have, scroll to the modes screen and tap the “Fermentation” icon. You can choose time and temperature there. You are able to set up to 12 hours.

    1. Hello Bev, instead of using a Thermoserver for fermentation, I utilise the fermentation mode on my TM6. You can use any type of food safe containers or jars during the fermentation process as the Thermomix will maintain a consistent temperature for you. Do you have a TM6?

  1. If using the Mix Shop yoghurt bottles, do you do the fermenting with the lids on or off.
