What is Black Onion? also called aged fermented black onion
Black Onion is a premium fermented food product created through a specialized high-temperature and high-humidity aging process that transforms fresh onions into a dark, sweet delicacy. This natural fermentation process takes 30-45 days, during which the onions develop their characteristic black color, soft texture, and complex flavor profile.
Unlike raw onions, Black Onion loses all its pungency and sharpness, developing a rich sweetness with subtle umami notes reminiscent of balsamic vinegar, tamarind, and molasses. The fermentation process also significantly enhances its nutritional value, making it a true superfood.
