Like many cooks who value the complex and sometimes unpredictable flavors of these homemade fermentations, Mr. Lee reaches for vinegar as an editing tool, using it to brighten and filter his dishes in delicate ways, boosting sauces and buoying broths.

The probiotic qualities of mixed bacterial/yeast olive fermentations are only recently being explored.

Yeast dominated fermentations produce a different suite of metabolites which have fewer self-preservation characteristics and therefore acid corrected, often with citric acid, in the final processing stage to achieve microbial stability.
