What causes pickling liquid to look cloudy?
Anti-caking ingredients in table salt make the liquid cloudy. That is why pickle recipes call for pure granulated salt. In fermented pickles, yeast development during fermentation causes cloudiness Cloudy liquid may also be a sign of spoilage. Before using the pickles, examine them for other signs of spoilage (spurting liquid, mold, off-odor, mushiness, slipperiness).
