Easy Classic Sauerkraut Recipe Your First Fermented Foods Project

Instructions:

1. Sanitize all equipment thoroughly with hot water and soap. Remove and set aside 2–3 outer leaves of the cabbage. Quarter the remaining cabbage, remove the core, and finely shred the leaves (1–2 mm thickness).
2. Place the shredded cabbage, measured salt, and caraway seeds into a large non-reactive mixing bowl.
3. Vigorously massage and squeeze the cabbage with clean hands for 5 to 10 minutes. Continue until a significant puddle of brine forms at the bottom of the bowl and the cabbage feels limp.
4. Transfer the salted cabbage mixture into the fermentation vessel in handfuls, pressing down firmly after each addition with a tamping tool to remove air pockets and help the brine rise.
5. Pour any remaining brine over the packed cabbage. Ensure the cabbage is completely submerged in the brine. If the level is too low, add filtered water until the cabbage is covered.
6. Place the reserved outer cabbage leaf on top of the packed shreds. Place the fermentation weight on top of this leaf, ensuring all shredded material remains under the liquid level.
7. Seal the jar with an airlock system or a standard lid lightly screwed on (allowing gas to escape).
8. Store the jar in a cool, dark location (18°C–22°C / 65°F–72°F). Monitor daily; small bubbles should appear after 2–5 days, confirming fermentation is active.
9. If any scum or film forms on the surface (harmless kahm yeast), carefully skim it off with a clean spoon, ensuring the cabbage remains submerged beneath the brine.
10. Begin taste testing the kraut around Day 10. Continue fermentation until the flavor meets your preference (typically 2–4 weeks).
11. Once satisfied with the flavor, remove the weight, secure the lid tightly, and transfer the jar to the refrigerator. Cold temperatures halt the fermentation process, preserving the kraut for months.
