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)

Understanding Black Garlic

Before diving into how black garlic can go bad if not stored properly, let's first understand what black garlic is and how it differs from fresh garlic.
