Make sure the water is no more than 30 °C when you mix it with flour, otherwise this can kill the good bacteria.
Put an elastic band around the glass to mark the start level and keep track of how much it is rising. We recommend using your fingers for mixing because the natural bacteria on your fingers can help activate the starter. If it has not doubled in volume after 3-5 hours on day 5, let it sit for another day and feed it again.
The sourdough starter consists of living bacteria, which work differently and makes it difficult to set fixed times for how it will develop. You can help the process by using warmer water at around 28-29°C and storing the starter in a warm place. When it has risen and developed air bubbles on the side of the glass as well as a sweet and lightly sour smell, it is a sign that it is active and ready for use.
Remember to take about 50 g of sourdough starter from the jar before baking. There will always be some leftovers that must be discarded in the process. Otherwise, you end up with a considerable amount of dough.
If the sourdough starter develops a pink or orange tinge on the surface, it is a clear sign that it has gone bad, and you need to toss it immediately. Clean the glass jar or container thoroughly and start over. You can also smell it; if it smells like rotten fruit, discard it right away.
If you need more recipes, you can take your favourite recipe for regular bread and convert it into sourdough bread. Just remember that you are not only adding yeast, you are also adding water, flour, bacteria and their acids, and much more, so you cannot convert it 1:1. Use, for example, our recipe for Danish rye bread but substitute the yeast – 25 grams – with about 150 grams depending on how much flour and water the bread has and how much there is in the starter, too. Try it out and change the amount each time until you have the perfect sourdough rye bread. In the case of rye bread, it does not have to be that active; it is more important to have a slightly older one with a higher amount of acetic acid.
Making sourdough at home almost feels like you are conducting a little science experiment with a lot of steps and pitfalls. Luckily, we have provided you with the necessary instructions and information to succeed; all you need is a little patience and a few basic ingredients.

Forget store-bought bread and pastries; this is the real deal! With our sourdough starter recipe, you can experience the delights of fluffy and airy baked goods with loads of flavour. You can get sourdough bread with the characteristic crispy crust, soft inner, and huge air bubbles – and of course the irresistible sour flavour that goes well with almost any topping and spread.
It is simple and easy – all you need is water, flour, and a little patience. Get your ingredients ready, find a clean glass jar and start mixing.
Before you can bake with the starter, you need to discard some of it and feed it with flour and water. Once it expands and produces air bubbles, it is ready to be put to use. You can also smell it; if it smells acidic like buttermilk, it is ready. The starter functions as a leavening agent, allowing bread and pastries to rise. So, if you are making bread, simply use your alive, bubbling, and ready-to-use starter and get started on, for example, this delicious sourdough bread with a crispy crust.
With the right conditions and lots of patience, your starter will eventually come alive, and you can get away with using most types of flour. Some flours have less rise but more flavour. To get the best result, it is a good idea to try different types so you can experiment with taste, aroma, and consistency and find the perfect balance of flavours and textures. Our recipe for sourdough starter contains rye flour and whole wheat flour. Rye flour ferments quickly and has a moist texture and a fruity flavour, and in addition, it has more natural bacteria, making it ferment quicker, while whole wheat provides a denser texture with complex flavours.
Want to ramp up the sour? Increase the acids depending on your personal taste. You can do a few things to increase the sourness. You can, for example, feed the starter less and starve the bacteria and yeast, thereby allowing the sourdough starter to produce hooch, a liquid that collects on top of the starter when it has not been fed for some time. But the easiest way to increase the sourness is to let the starter ferment longer than you normally would, creating more acetic acid, which you, among others, know from vinegar.
Sourdough does not have to be that sour. Remember to feed the starter regularly, do not allow it to produce hooch, and shorten the time that it ferments. In reality, you have to do the opposite of what is described above to make the sourdough starter less sour.
A good rule of thumb is to know it by the smell. When it is young and fresh, it smells like buttermilk, and when it is older and more fermented, it will smell like vinegar and even alcohol.
Why toss leftover starter when you can put it to good use? If you use the discard right away, it will still be active and bubbly. However, if you store it for later use, it will be less active and not give a good rise. But rest assured, you can simply pair it with baking powder and soda and still get an airy and fluffy result.
If you use it as is after discarding, you can simply add it to most recipes, taking into account how much flour and water you add since this is already a part of the sourdough discard. Simply put, divide the amount of starter in two, then deduct this from the amount of flour and liquid in the recipe. For example, use our recipe for American pancakes. If you have 100 grams of sourdough discard, only use 250 grams of flour and about 250 grams of milk (since the recipe opts for 300 ml of milk). Make the recipe as is without changing anything else but the amount of flour and milk and adding starter. You will still get risen, beautifully fluffy American pancakes but with a more complex flavour.
