Ground onion is a type of spice obtained by drying and grinding white onions. When onion powder is made, the water in the onion evaporates and only the essence of the onion remains. Therefore, onion powder has high nutritional values. Ground onion does not have a strong odor like fresh onions, but it is rich in aroma. It is a type of spice that can be a favorite especially for those who do not want to consume fresh onions for various reasons.
