Description
Precision-controlled acid penetration using vacuum sealing and low-temperature baths to accelerate flavor infusion while preserving texture.
Technical
Utilizes vacuum pressure to remove air pockets and facilitate marinade penetration via Fick's laws of diffusion. Acid (typically acetic or lactic) denatures proteins while low temperature (40-60°C) prevents overcooking. Often includes osmotic agents (salt/sugar) to balance water activity.
Culinary Significance
Creates crisp-tender pickles with vibrant flavors in hours instead of weeks. Enables novel combinations like sous-vide pickled strawberries or rapid kimchi. Maintains cell structure better than boiling brine methods, preventing mushiness.
Parameters
Temperature
°C to °C range
Higher temps accelerate but risk texture loss
Time
4-12 hours (typical for 5mm slices)
1 hour (thin slices) – 72 hours (dense roots)
