How do you ferment yogurt at home?

Methods for fermenting yogurt at home

With regular practice, the yogurt-making process becomes even easier; after a while, it’s less about measurements and more about muscle memory. Some things in the kitchen start with a recipe, then adapt to your own rhythm. Yogurt is exactly one of those things.

When it comes to making yoghurt at home, there isn’t just one way to do it. The container you use, the amount of milk, your choice of starter culture and how you leave it to set all affect the result. That’s why choosing the technique that suits you best from the various methods of making yoghurt at home is a good place to start.

Fermenting yogurt using the traditional method

This method stands out as the most well-known recipe for making yogurt. It is particularly practical for those wishing to make yogurt at home for the first time.

• Bring the milk to the boil in a deep saucepan.
• Once it has boiled, simmer for a few more minutes. This step helps to thicken the mixture.
• Remove the milk from the heat and leave it to cool to the right temperature for making yoghurt.
• In a separate bowl, mix the yoghurt starter with a few spoonfuls of the warm milk until smooth.
• Add the starter mixture to the milk and stir gently.
•Cover the saucepan, wrap it in a clean cloth and leave it to set.

In this classic method, the time required for the yoghurt to set generally varies depending on the ambient conditions. If you’re in a great hurry, the result might be a bit temperamental; yoghurt has its own pace.

Yogurt fermentation in jars

If you like portioning your yogurt, using jars to make yogurt at home is very practical. Glass jars, in particular, are a good choice for both hygiene and ease of storage.

• Leave the boiled milk to cool to the right temperature for fermentation.
• Dissolve the starter culture in a small amount of milk in a small bowl.
• Combine the mixture with the milk.
• Divide the milk between the jars.
• Loosely cover the lids or cover the tops.
• Leave the jars to rest in a stable place without shaking them.

This method is particularly suitable for those looking for a home-made yoghurt recipe and wishing to prepare small portions. You can then place the jars directly into the fridge.

Fermenting yogurt in a food container

For those who wish to prepare a batch at a time and store it regularly, food containers offer a practical solution. You can streamline the yogurt fermentation process using large-capacity food containers. Containers with secure lids are particularly advantageous for storing the yogurt after fermentation.

The key point to note here is that the container must be clean and dry. Furthermore, opting for containers of a moderate size that maintain heat evenly, rather than very deep ones, can improve the results.

Fermenting yogurt by leaving it in the oven

In some kitchens, the room temperature can fluctuate. In such cases, the enclosed space of the oven can provide a stable environment. Placing the fermented milk inside the oven and leaving only the light on can ensure a controlled fermentation process. This method is also frequently mentioned among the tips for making yogurt at home.

Making yoghurt without starter cultures

If you don’t have traditional yoghurt starter, you don’t have to give up entirely. To make yoghurt without a starter, some people use chickpeas, chilli stalks or the by-products of previous natural fermentations. The result may be more variable than with the traditional method; however, it is an interesting option for those who enjoy experimenting with natural processes.

What should you bear in mind when making yoghurt at home?

To ensure a successful yogurt fermentation process, there are a few key points to bear in mind. Firstly, the quality of the milk is very important. Using fresh milk makes it easier to achieve a more consistent texture. Secondly, you must not use too much starter culture; using too much will not yield better results, but may actually affect the taste.

Another important factor is maintaining the right temperature during the fermentation process. If the starter culture is added whilst the milk is too hot, it may lose its viability. Conversely, if the temperature is too low, fermentation may slow down and the desired consistency may not be achieved. For this reason, temperature control is the most crucial aspect of making yoghurt at home.

The cleanliness of the container, ensuring the spoon used is dry, and avoiding shaking the fermenting mixture during the resting period are also important. In short, making yoghurt at home requires a bit of care, but it is a highly satisfying process for those who enjoy keeping their kitchen tidy.

How long does it take to ferment yogurt at home?

The fermentation time for yogurt usually ranges from 4 to 8 hours. Whether the environment is cool or warm directly affects this time. Those who prefer a thicker consistency generally choose to wait a little longer. However, leaving it out for too long can cause it to become overly sour.

Generally, 5–6 hours is a good starting point for making yoghurt at home. Rather than consuming the yoghurt immediately after it has set, allowing it to rest in the fridge for a few hours helps the texture to settle. In other words, a short rest period after the yoghurt has set is beneficial; yoghurt likes a bit of peace and quiet too.

At what temperature does milk ferment?

The fermentation temperature for yoghurt is one of the most critical factors. Generally, milk is fermented when it reaches a temperature that is not hot enough to burn your hand but is noticeably warm. If you are using a kitchen thermometer, the recommended fermentation temperature range for most recipes is around 42–45 degrees.

This range helps the culture remain active during the fermentation process. At too high a temperature, the culture may be damaged; at too low a temperature, fermentation proceeds slowly. Therefore, it may be safer to measure the temperature rather than guess when it comes to the temperature for making yoghurt.

What is the best container for making yoghurt?

The best container for making yoghurt at home is one that retains heat evenly, is easy to clean and is suitable for food contact. Glass jars are often preferred for this purpose as they do not retain odours and allow for portion control. Large storage containers are also very practical for larger families.

For those who prefer a more traditional method, saucepans can be a good starting point. In particular, models with thick bases help maintain a more even temperature when making yoghurt in a saucepan. During the storage phase, steel food containers can be a useful option.

How do you make yoghurt in a pot?

Making yoghurt in a pot is one of the most traditional methods in the kitchen. What’s more, as it’s all done in a single pot, it ensures a consistent process.

First, bring the milk to the boil in a suitable saucepan. Then, leave the milk to cool to the right temperature for setting. In a small bowl, thin the yoghurt with a few spoonfuls of milk and add it to the saucepan. Stir the mixture gently, without stirring too quickly. Then cover it, wrap it in a cloth and leave it in a stable place.

The more evenly the pots used here retain heat, the more consistent the result will be. It is particularly important not to move the pot during the fermentation process.

How do you make yoghurt using store-bought yoghurt?

This is one of the most common methods. In this yoghurt recipe, plain, fresh store-bought yoghurt is used as the starter. The key here is that the yoghurt used must be additive-free and contain live cultures.

Mix one or two tablespoons of yoghurt with milk in a small bowl until smooth. Then add this mixture to the main batch of milk. This way, you’ll be putting one of the most practical answers to the question ‘how to make yoghurt’ into practice. This method is particularly reassuring for those new to making yoghurt at home.

How much yoghurt starter should be added to 5 kg of milk?

As a general guideline, approximately 4–5 tablespoons of yoghurt starter should be sufficient for 5 kg of milk. Using too much starter does not, contrary to what one might expect, result in a better consistency. Using a balanced amount helps to achieve a smoother texture when making yoghurt.

Here, the type of milk and the strength of the starter culture used can also play a role. Therefore, it is a good approach to keep the measurement balanced during the first attempt and observe the result. One of the most useful habits among home yoghurt-making techniques is getting to know your own kitchen routine.

How much yoghurt starter should be added to 2 litres of milk?

Generally, 1 to 2 tablespoons of yoghurt starter is sufficient for making yoghurt from 2 litres of milk. Rather than using a very concentrated starter, proceeding with the correct temperature and the right waiting time yields better results. Making yoghurt from 2 litres of milk is an ideal quantity for small families and first attempts. This allows you to monitor both the fermentation time and the consistency more easily.
