A sweet onion can be identified by its flatter shape and looser, less papery skin, and especially by its broader and tighter neck.
Here's a breakdown of how to choose a sweet onion:
- Neck Size: Look for onions with tight, narrow necks. Sweet onions have tighter necks.
- Texture: Sweet onions tend to have more moisture, making them a bit softer to the touch.
- Variety: Walla Walla, Maui, and Spanish onions are popular sweet onion varieties.
