The Difference Between Sweet Onion and Regular Onion

Regular onions, on the other hand, have a stronger and more pungent flavor. They are often used in cooked dishes and are an essential ingredient in many recipes. Additionally, sweet onions have a higher sugar content and a lower sulfur content than regular onions, which gives them their characteristic sweet taste and reduces the likelihood of causing tears when cutting them.

Storage Tips for Sweet Onion

Sweet onions should be stored in a cool, dry place such as a pantry or cellar. Do not refrigerate sweet onions as the cold temperature can soften the texture of the onion and cause it to spoil more quickly. If you cut a sweet onion and don't use the entire onion, wrap the remaining portion tightly in plastic wrap and store it in the refrigerator for up to 5 days. If you have an abundance of sweet onions, you can also chop and freeze them for later use in soups, stews, and casseroles.
