How to make fermented cucumbers

Ferment cucumbers yourself - it's easy with our recipe!

It's just cucumber season again - the perfect time to Ferment cucumbers! We are already in the middle of fermentation fever ... 🙂

(For the impatient: Here you can find the recipe!)

Even if we haven't really been able to bring in huge cucumber harvests on our own balcony - great cucumbers grow in the garden of Till's parents, and otherwise we are always happy at the market 🙂

In general, we are really big cucumber fans - both raw as a snack, in a salad, on bread, as stewed cucumbers ... they are just super versatile! And especially in summer, cucumbers are super refreshing, crunchy and, with their high water content, a great companion on hot days.

But cucumbers can do a lot more! If you ferment them lactic acid, they not only convince with a great aroma, but also with many Lactic acid bacteria. 🙂 Spiced up with spices such as mustard or dill, they are reminiscent of pickles - and are a great side dish for grilling or as a topping for burgers and hot dogs.

But cucumbers are not only delicious - they can also convince with their ingredients!

Why are cucumbers healthy - and what should you watch out for when eating them?

Cucumbers as a slimming agent - who hasn't heard that before? That's because cucumbers a lot of water and are therefore very low in calories. If you (like Till) have problems drinking enough water - just pick up the cucumber more often!

What nutrient Concerned, cucumbers can mainly by Vitamin K score, other vitamins and minerals (such as magnesium, potassium and B vitamins) are also available - but in smaller quantities.

By the way, in order to get as many nutrients and fiber as possible, you should eat the cucumber with its skin - there is a lot of good in it 🙂

But cucumbers also contain bitter substances - namely Cucurbitacins. Since cucurbitacins can cause gastrointestinal intolerance or worse even in small amounts, these substances were specifically "bred out" of the cucumbers. The vast majority of cucumber varieties today hardly have any cucurbitacins - but even today cucumbers can produce more bitter substances under severe stress (this is rarely the case).

It is therefore important: The bitter substances accumulate on the stem of the cucumber - you should therefore cut away the end of the cucumber if it has a bitter taste and not eat it. And especially important: If a cucumber tastes particularly bitter - dispose of it completely and do not eat!

What are the benefits of fermenting cucumbers?

As with other fermented vegetables, the main focus here is on microbes - namely the lactic acid bacteria that cause the Lactic acid fermentation arise!

In short: When fermenting, we create certain conditions (salt concentration, temperature, oxygen concentration) that promote the growth of certain lactic acid bacteria. This makes the ferment durable and creates the typical lactic acid taste. You can also find more information on this topic in our article “What is fermentation”.

Fermented cucumbers are therefore not only delicious - they are also "lively“And full of lactic acid bacteria that probably have one positive effect on your intestines to have!

Which type of cucumber is best for fermenting?

Cucumbers belong to the cucurbit family and there are essentially 2 types - snake cucumbers and pickled cucumbers!

Snake cucumbers are long and thin and nowadays mostly the "standard cucumber". They have a relatively thin skin and contain a lot of pulp - therefore, in our experience, they are not very suitable for fermentation.

Pickling cucumbers are small and thick, with a firmer shell. Perfect for fermenting!

Your pickling cucumbers should have the following properties:

  • rather small - then there is less pulp. This means that the cucumbers will not be so soft later during fermentation.
  • firm and plump - soft cucumbers become even softer in consistency through fermentation.

And now - let's start with the recipe!

  • untreated salt

And here's a short one FAQ with your most common questions:

What is the difference to pickled cucumbers?

Pickled cucumbers are usually not fermented, but rather pickled with vinegar - so they are classically "pickled cucumbers". However, this also means that lactic acid fermentation does not take place and you have no “living” ferment!

How long do fermented cucumbers keep?

Fermented cucumbers can be stored unopened in the refrigerator for several months. Even after opening, they will keep for several weeks in the refrigerator - make sure you only remove them with clean cutlery!

How long do the cucumbers have to ferment?

We ferment cucumbers for 7-14 days, depending on the desired taste and consistency. Then they go to the fridge 🙂

My cucumbers are very soft after fermentation - what can I do?

Since cucumbers mainly consist of water, they quickly become relatively soft when fermented - so that's quite normal at first. For “crunchier” cucumbers, you can choose a slightly higher salt concentration (4-4.5%). Also, be sure to remove the ends of the cucumbers.
