People have been making fermented foods for thousands of years. Long before anyone had heard the words "bacteria" or "microbiome," people had already discovered that fermentation preserved food, improved its flavour and often made it more nutritious.

Fermentation is simply a natural process where beneficial microorganisms transform food.

As they do that, they create compounds that not only change the food itself but may also help support the incredible ecosystem living inside us.

Sauerkraut is one of the simplest and healthiest fermented foods you can prepare at home

ingredients

. 1kg fresh cabbage

. 20 g kosher salt

. 1 teaspoon whole cumin sees (optional)

Method

1-Remove the damage outer leaves from the cabbage and set one clean leaf aside.

2- Finely shred the cabbage and place it in a large bowl.

3-Add kosher salt and cumin seeds.

4- massage the cabbage with your hands for 5 to 10 minutes. as you massage it, the cabbage will soften and being released its liquid, creating a natural brine.

5- Pack the cabbage firmly into a clean glass jar, pressing down well after each handful to remove any trapped air.

6- por any remaining brine from the bowl into the jar. The cabbage should be completely submerged beneath the liquid.

7- Place the reserved cabbage leaf over the shredded cabbage and use a fermentation weight or a small clean glass to keep everything below the surface of the brine.

8- loosely close the lid, or use a fermentation lead if you have one.

9- leave the jar to ferment at room temperature, ideally between 18-22°C, away from direct sunlight.

Fermentation Time

. About 5-7 days for a mild, fresh flavour.

. About 2-3 weeks for a richer, more traditional sauerkraut.

Teste it whenever you like. Once it reaches the flavour you enjoy, transfer it to the refrigerator, where it will keep fermenting very slow.

What to Expect

During fermentation you should see small bubbles, the brine may become slightly cloudy, and the aroma should become pleasantly sour. These are sign that the beneficial bacteria are doing their work.

The most important rule is simple: always keep the cabbage completely submerged beneath the brine.
