What You Need to Know
Halophilic lactic acid bacteria (e.g., Lactobacillus plantarum) metabolize citric acid and sugars, producing lactic acid (1.2-2.1% final pH 3.0-3.5) while enzymatic breakdown of pectin softens rinds.
Preserved lemons add bright acidity and deep savoriness to tagines, dressings, and grain dishes without added vinegar.
