Red onions are a variety of onion known for their deep purple-red skin and white flesh with reddish layers. They have a milder, slightly sweeter flavor compared to yellow onions, making them a popular choice for raw preparations like salads, salsas, and sandwiches. When cooked, red onions become milder and sweeter, making them ideal for grilling, roasting, or caramelizing. Their vibrant color also adds a visual appeal to dishes. Red onions are rich in antioxidants, particularly anthocyanins, which give them their distinctive color and provide potential health benefits, such as supporting heart health and reducing inflammation. They can be used both in savory and pickled forms, and their versatility makes them a staple in many cuisines worldwide
