Why Does Garlic Turn Blue When Pickled?

The science behind this effect is related to the same things that give garlic its signature odor and taste.Garlic contains an odorless sulfur compound called alliin.When you cut or crush the garlic, the alliin and alliinase are mixed, creating an organosulphate compound called allicin.Three pyrroles linked together creates blue.Garlic that has turned blue or green during pickling or cooking is perfectly safe to eat, and the presence of color has no effect on the garlic's flavor.If you want to avoid the blue or green color when pickling garlic, try the following solutions. .

Blue and Green Garlic Is Okay

Naturally occurring sulfur in the garlic interacts with those enzymes, occasionally turning it slightly green or blue.Shifts in temperature, pH, and the age of the garlic can also come into play, so heating it or mixing it with acid might have some affect.Anytime you cook garlic or onions in a high-acid solution—say you sauté them, then deglaze the pan with lemon juice—this issue could occur.LaBorde also suggests blanching: "Try putting them in hot water for a short period of time, which might slow down or inactivate the enzymes.". .
