Can Black Garlic Go Bad If Not Stored Properly?
Black garlic is a unique and flavorful ingredient that has gained popularity in recent years for its rich umami taste and health benefits. Made by fermenting regular garlic bulbs at a specific temperature and humidity over several weeks, black garlic undergoes a transformation that results in a sweet, tangy flavor with a soft, jelly-like texture. While black garlic has a longer shelf life compared to fresh garlic, proper storage is essential to maintain its quality and prevent it from going bad. (Black garlic)
