Description
A purple onion, also commonly called a red onion, is a variety of onion known for its distinctive reddish-purple skin and white flesh with streaks of red or purple. Here’s a detailed description:
Appearance:
-
Skin: Thin, papery outer layers that are deep purplish-red.
-
Flesh: Crisp, with alternating white and purple rings inside.
Flavor:
-
Raw: Mildly spicy, sharp, and slightly sweet; less pungent than yellow or white onions.
-
Cooked: Becomes sweeter and milder in flavor; the color may fade when sautéed or roasted.
Culinary Uses:
-
Often used raw in salads, salsas, sandwiches, and pickles for color and crunch.
-
Also used in grilled or roasted dishes, and can be caramelized for a sweeter flavor.
Nutritional Highlights:
-
Contains antioxidants such as quercetin and anthocyanins (which give the onion its purple hue).
-
Low in calories and a source of vitamin C, fiber, and other phytonutrients.
Fun Fact:
Despite being called a “red” onion in many countries, its color is clearly purple—hence the alternate name “purple onion.”
