What are the main differences between sweet onions and regular onions?
Sweet onions and regular onions have several distinct differences in terms of their flavor, texture, and usage in cooking. Sweet onions, such as Vidalia or Maui onions, are known for their naturally sweet and mild flavor, which makes them ideal for eating raw or using in dishes where a sweet onion flavor is desired.
