Homemade Natural Yoghurt Recipe

My homemade natural yoghurt recipe is super simple if you are able to invest in the equipment you need. We rely on these yoghurts as our default dessert in our home – they are quite simply always in our fridge. The plain yoghurt recipe below is the one I use most often – I make a batch three or four times a week – but once you have tried these, you will certainly want to try out the many other yoghurt flavours and variations.

I wanted to post my yoghurt recipes, for anyone else out there who would like to give it a go and are not finding much UK-based or English-language information. I’ve also tried to be more specific than many recipes about quantities, as it’s often useful for family cooks to be able ring the changes with what pots they have available and how much milk they have to use.

I grew up eating homemade yoghurt – which was unusual at the time in the UK – due to French influences in our family. It is still much less common for people to make their own yoghurt in the UK than it is in France, largely because of the unnecessary complexity of many UK recipes.

This method takes just 5 minutes of your engaged time for delicious homemade yoghurt, and there is no need to measure temperatures!

 

Here are all the details of the yoghurt making ingredients and process – or see further down for the brief, printable yoghurt recipe.

Ingredients for Homemade Yoghurt

The ingredient list for your homemade yoghurt is hardly even a list! All you need is a ‘starter’ yoghurt and some milk.

Starter Yoghurt

To start your yoghurt fermentation, you need a plain natural yoghurt containing ‘live’ cultures. It doesn’t matter if you buy the ‘set’ type, or ‘Greek-style’, or the higher protein types, really anything seems to work. You just need to check that the only ingredient is yoghurt (no thickeners, sweetners, etc) and that it mentions live cultures. Choose a full fat yoghurt for best results. I tend to buy a 150g pot of a well known brand of organic yoghurt, easily available in most UK supermarkets.

You can freeze yoghurt for use later as a starter, although I find it doesn’t tend to work quite as well after being frozen. If I’m buying a new starter, sometimes instead of buying the small 150g yoghurt that will make one batch of yoghurts, I will buy a 500g tub, and portion it out into 125g lumps to freeze for future starters. You just have to remember to defrost it in good time for when you need it (microwaving it to defrost will likely kill the live cultures).

Once you have made a batch of yoghurts, you keep one pot of the batch (or 120-150g) aside to be the starter for the next fermentation, so you are not buying a new starter each time. After a perhaps three weeks of three-four batches a week I usually find my yoghurts aren’t as well set or have a grainy texture, and I will then start again with a new supermarket starter.

If you strain a batch of yoghurts to make thicker ‘Greek-style’ yoghurt, you will be left with whey which also contains the active yoghurt cultures. Whey can also be used to start a batch of yoghurts, though I tend to use it only for drinking yoghurts where a strong set is not desired.

The alternative to using a starter yoghurt, is to buy yoghurt starter cultures in powder form. These are convenient, as they can sit in your cupboard until you need them when you find you have accidentally eaten your starter yoghurt. These are easy to find in French supermarkets, but take a little more tracking down in the UK. You can try an online French grocery store for these Alsa yoghurt starter cultures I have used with 100% success for years. Similar products are available on a famous online retail site – they are more expensive and I was extremely disappointed by the ones I bought (a pandemic-forced purchase) as the yoghurts didn’t set at all.

Milk

For the milk for your yoghurts you will need UHT milk. Use it straight from the cupboard at room temperature. Use whole milk for well-set, tasty yoghurts. Semi-skimmed milk won’t set as firmly and may require longer fermentation.

If you use fresh (chilled) milk, you will need to heat it to a particular temperature and cool it back to room temperature. I have done this a couple of times, and a good quality fresh milk does make even more delicious yoghurt, but it takes so much attention and time (the cooling in particular) that it is not something that is viable for me on a regular basis. I don’t own a food thermometer.

Most UK recipes talk about heating and cooling the milk in this way, whereas most French recipes don’t – this is because by default “milk” in France means UHT milk. Bear this in mind if using French yoghurt recipes – if you substitute fresh milk, you must heat it first to ensure it is safe. This is possibly one reason why yoghurt-making is more common in France.

Keeping UHT milk in the cupboard means you are always ready to whip up a batch of yoghurt in just a few minutes. (We currently buy 50 pints of fresh milk a week, which we drink: I tend to use UHT for milk puddings, custard, white sauces, blancmanges, etc, so as not to deplete our fresh milk supply and because then you are also not wasting energy heating up chilled milk.)

 

Other additives

Most commonly, you will see recipes calling for you to add powdered milk to the mixture. I do this sometimes, and it can improve the set of your yoghurt, particularly if your culture is getting old, but I don’t find it necessary. It will help your yoghurt set if you have to use semi-skimmed milk. If you do add it, make sure you stir it in very well, and even leave your mixture to sit for a while before pouring it into individual pots.

If I have the end of a pot of cream, crème fraîche or evaporated milk sitting about (perhaps a tablespoon or up to 1/4 cup), I will sometimes add this to the mix. The creams in particular will improve the flavour and texture of your finished yoghurts significantly.

Equipment / Fermentation Method

This homemade natural yoghurt recipe is based around using a yoghurt maker. I grew up with one in regular use at home in the UK, which was unusual at the time, and is still pretty unusual. These items are much more commonly owned and used in France.

Searching for homemade natural yoghurt recipes in the UK will return results talking about ‘Thermos’-type flasks, ‘Kilner’-type jars, casserole dishes wrapped in towels, food thermometers, airing cupboards, radiators and so on. All of that terrifies me, and if that were what was required, I wouldn’t blame people for never making their own yoghurt – I certainly wouldn’t.

A yoghurt maker is a very simple machine, that just keeps things at a constant low temperature for a given amount of time. To be honest, yoghurt ‘maker’ is a bit of a misnomer – it makes it sound as if it does more than it does. You make the yoghurt, the machine just keeps it warm for you.

I happen to have a large and fairly elaborate yoghurt maker that also does other things, but basic models for 6-8 yoghurt pots can be had quite cheaply.

This is (a newer version of) the model I have: Yaourtière SEB Multi delices. It was the size and the fact it has space for large tubs that sold this one for me. If I could only make six small pots at a time, my entire life would be yoghurt-making!

Here is an example of a small yoghurt maker at a UK retailer.

The related benefit I think of having a machine, is that you get the pots, tubs, strainers, lids, etc to fit. Particularly useful in our family are the plastic drinking-yoghurt bottles designed for our machine, which allow me to provide the kiddies with spoon-free drinking yoghurts for packed lunches.

Empty your starter yoghurt into a large bowl (one with a pouring lip is helpful) or jug. 150g of yoghurt is enough starter for up to 2 litres of milk.

Add the milk, starting with a little at a time.

Making your own natural yoghurt

I have read that results are improved by letting the mixture stand for a little while at this stage, but I have never tested this scientifically.

Pour or ladle the mixture into your pots/tubs, aiming for an even fill.

Place your pots into your yoghurt-maker following the manufacturers instructions, and set the fermentation time.

My yoghurt maker can be used for up to 12 150ml pots, or for two 1-litre tubs. If I use pots alongside a tub, I have to balance the pots on an old ice-cream tub lid which you can see on the left here!

8 hours fermentation is probably the minimum required when using whole milk; semi-skimmed milk will need a longer fermentation to achieve the same texture. The longer the fermentation time, the firmer the set (yoghurt with corners) and the more complex the flavour.

Experiment by setting a batch of yoghurts to ferment for 12 hours, and remove a couple of yoghurts at the 8 hour and 10 hour points, and see which you prefer.

Once the fermentation time has completed, cool your yoghurts on the kitchen side and then cover and transfer them to the fridge. They’ll need a couple of hours to get properly cold before you can eat them.

Straining your Yoghurt for a Thicker Result

If you’d like a thicker, ‘Greek-style’ yoghurt, you can strain your yoghurt after the fermentation process finishes. Either use the strainer(s) provided with your yoghurt maker, or you can line a sieve with cheesecloth, spoon the yoghurt into that, cover and stand it over a bowl or saucepan in the fridge. Strain for a few hours or overnight. You might be surprised at how much whey (the clear liquid that drips out of the yoghurt) you get! See my post on what to do with your leftover whey.

Saving Money by Making Your Own Yoghurts

Making your own yoghurt will save you money, even taking into account the electricity used, compared even with the cheaper supermarket yoghurts, because, basically, milk is cheaper than yoghurt. You will also have much nicer yoghurt for the price. It saves you money even if you buy your starter yoghurt each time (see below) but the savings increase each time you use one of your own yoghurts from the previous ’round’ as your starter.

Homemade
1 Litre UHT Whole Milk£0.71
150g Organic Plain Yoghurt£0.55
Electricity (approx.)£0.30
Total£1.56c1000g16p per 100g
Supermarket Own-brand Plain Yoghurt£0.95500g19p per 100g
