Sweet onions range in color from white to yellow. While some varieties may exhibit a pale yellowish hue, the most common color associated with sweet onions is a light yellow. They often have a flattened or squashed appearance, differing slightly in shape from other onion types. The color can vary depending on the specific type of sweet onion, such as Vidalia, Walla Walla, or Maui onions, all known for their sweetness and mild flavor.
Types of Onions and Their Colors:
- Sweet Onions: Primarily white to yellow. Examples include Vidalia, Walla Walla, and Maui onions. These are known for their mild flavor and are often eaten raw.
- Yellow Onions: These have a balance of sweetness and pungency, becoming sweeter when cooked. They are a common choice in many dishes.
- White Onions: Similar to yellow onions, but with a slightly sharper flavor when raw. They are not as sweet as yellow onions, even when cooked.
- Red Onions: These onions have a purplish-red skin and are known for their relatively mild, sweet flavor. They are frequently used in salads and salsas.
The sweetness of an onion is not solely determined by its color; various factors contribute to its flavor profile. However, many of the commercially popular "sweet onions" tend to have a light yellow or white color.
Storing Sweet Onions:
Sweet onions are more perishable than other types and should be stored in the refrigerator to maintain their freshness.
