Fermentation

Exceptional FERMENTATION Rank #1 Value: 9.80 Nécessite une validation Confidence: 10%

Sensory Profile

tangy umami-rich complex acidic

Molecular Foundations

This technique works primarily through microbial_bioconversion. Key molecules involved include lactic acid, acetic acid, ethanol. The process creates flavor compounds through microbial_bioconversion.

Key Ingredients

Chef's Note

"Patience is the secret ingredient — let time do the work."

How to Execute

Level: intermediate

Preparation

1
Sanitise vessel and tools 10min

Clean and sanitise fermentation vessel, weights, and any tools that contact the product. Use starsan or boiling water.

Equipment
fermentation vessel airlock or cloth cover weights thermometer pH meter
2
Prepare substrate 20min

Prepare the substrate: brined vegetables, salted meat, inoculated dairy. Ensure proper salt concentration.

Failure: Surface mould — insufficient brine coverage
→ Ensure substrate is fully submerged; use brine weight to keep submerged

Execution

1
Create anaerobic environment 5min

Pack substrate tightly into vessel. Fill with brine to completely submerge. Use weight to keep submerged.

✅ Checkpoint: No exposure to air; brine covers all surfaces
Pass criteria: Substrate fully submerged; no floating pieces
2
Seal and ferment 1440min

Seal with airlock (for vegetables) or cloth cover secured (for dry ferments). Store at target temperature.

✅ Checkpoint: Active fermentation visible (bubbles, aroma shift)
Pass criteria: pH drops to target range; aroma is clean and acidic, not putrid

Common Failures

Kahm yeast (surface film)
Too salty — salt ratio too high

Pro Chef Tips

Temperature drives speed and character Higher temps (22–26°C) = faster fermentation, more acidic. Lower temps (12–16°C) = slower, more complex.
Reserve brine as starter Save a tablespoon of finished brine to kick-start your next batch — it seeds the right bacteria.
