Fermentation is one of the oldest methods of processing and preserving food. Long before the advent of refrigerators, people fermented vegetables, made cultured dairy products, sourdough bread and naturally fermented beverages.
During fermentation, microorganisms process the sugars contained in foods and create organic acids, gases and other compounds. This is precisely why cabbage turns sour, dough rises, and ordinary vegetables acquire a deeper and richer flavor.
Today fermentation is experiencing a rebirth. It is no longer just sauerkraut, pickled cucumbers and kombucha, but also fruit-and-vegetable combinations, unusual sauces, fermented seasonings and products with a vibrant umami flavor.
What are the benefits of fermented foods?
Fermentation partially breaks down certain complex compounds, so some foods may become easier to digest. Lactic acid bacteria create an acidic environment that helps foods keep longer and shapes their characteristic flavor.
Unpasteurized fermented foods may contain live microorganisms. Together with the fiber from vegetables, they support a varied diet and create favorable conditions for the gut microflora.
During fermentation, the availability of certain nutrients also changes, and the flavor becomes richer without a lot of sugar, vinegar and artificial additives.
However, fermented foods are not a medicine. Their benefits depend on the composition, the method of preparation and the individual characteristics of the person. Moreover, because of their salt content, they are best consumed in moderation.
What's new in fermentation in 2026
The main trend is not simply to preserve the harvest, but to create a new flavor. Acidity combines with sweetness, pungency with fruity notes, and familiar vegetables acquire an unexpected aroma.
Especially popular are fermented sauces, combinations of vegetables with fruits and citrus, local products instead of expensive exotic ingredients, and the use of those parts of plants that used to be thrown away.
Here are a few interesting recipes that you can recreate at home.
Cabbage with beet, pear and juniper
Fruit-and-vegetable fermentation is one of the most beautiful trends of the year. Pear softens the acidity, beet gives a rich color, and juniper adds a light forest aroma.
Ingredients:
- 700 g cabbage;
- 200 g beet;
- 100 g firm pear;
- 20 g salt;
- 5–6 juniper berries.
Shred the cabbage, and cut the beet and pear into thin julienne strips. Add the salt and massage with your hands until juice appears. Pack tightly into a jar and place a weight on top.
Ferment for 5–10 days, making sure the contents remain under the liquid.
Cauliflower with curry, garlic and lemon
After fermentation, cauliflower turns into a bold, crunchy snack with a spicy and slightly nutty flavor.
Ingredients:
- 600 g cauliflower;
- 2 garlic cloves;
- 1 teaspoon turmeric;
- ½ teaspoon mustard seeds;
- a piece of lemon zest;
- 700 ml water;
- 14 g salt.
Break the cauliflower into florets, put them in a jar together with the spices and pour over the brine. Leave for 5–8 days, and once a pronounced sour taste appears, move it to the refrigerator.
Fermented pepper and plum sauce
Instead of the usual hot honey, more complex sauces are coming into fashion, in which pungency combines with acidity and fruity sweetness.
Ingredients:
- 300 g sweet red pepper;
- 100 g hot pepper;
- 150 g pitted plums;
- 2 garlic cloves;
- 11 g salt.
Chop the ingredients, mix with the salt and pack tightly into a jar. If necessary, add a little two-percent brine.
Ferment for 4–7 days, then blend with a blender and store in the refrigerator.
Radish with grapes and pink pepper
An unusual combination of pungent radish, sweet grapes and the floral aroma of pink pepper.
Ingredients:
- 400 g radish;
- 100 g firm grapes;
- 1 teaspoon pink pepper;
- 500 ml water;
- 10 g salt.
Cut the radish in half, put it in a jar together with the grapes and pour over the brine. Ferment for 3–5 days, then move it to the refrigerator.
Fermented green salsa
Live fermented sauces are becoming one of the main alternatives to the usual marinades and store-bought seasonings.
Ingredients:
- 500 g green tomatoes;
- 1 sweet peppers;
- a little hot pepper;
- 2 garlic cloves;
- a small bunch of cilantro;
- 12 g salt.
Chop the vegetables, mix with the salt and pack tightly into a jar. Leave for 3–5 days, then blend with a blender and put in the refrigerator.
Carrots with orange, ginger and coriander
After fermentation, crunchy carrots become pleasantly sweet-and-sour, while the orange zest gives them a bright aroma.
Ingredients:
- 500 g carrots;
- a strip of orange zest without the white pith;
- 15 g fresh ginger;
- 1 teaspoon coriander seeds;
- 500 ml water;
- 10 g salt.
Cut the carrots into batons and pack them tightly into a clean jar together with the ginger, coriander and zest. Dissolve the salt in the water, pour it over the vegetables and place a small weight on top.
Leave at room temperature for 4–7 days. When a pleasant sour aroma appears, move it to the refrigerator.
Important rules
For vegetables it is convenient to use about 2% salt of the total weight of the products and water. For one kilogram of the mixture you will need approximately 20 grams of salt.
All the products must remain under the brine at all times. During active fermentation, the jar must not be sealed hermetically if the lid does not have a valve for gas to escape.
Bubbles, a sour aroma and cloudiness of the brine usually accompany normal lactic acid fermentation. Coloured fuzzy mould, a putrid smell or pronounced slime are grounds to throw out the contents entirely.
The finished products must be stored in the refrigerator. Home fermentation does not turn them into preserves that can be left at room temperature for months.
Fermentation in 2026 is a genuine home laboratory of taste, where carrots meet orange, cabbage meets pear, and hot pepper meets plum. And the most interesting gastronomic discoveries now begin not in an expensive restaurant, but in an ordinary glass jar in the kitchen.
