These are red onions, a variety of the common onion known for its distinctive purple-red skin and flesh. They have a slightly milder flavor than yellow onions, with a subtle sweetness that becomes more pronounced when cooked. Red onions are a staple in many kitchens, prized for both their visual appeal and their taste.
Red onions add color and flavor to a wide range of dishes, from raw preparations to slow-cooked meals.
When preparing red onions, you can use them raw, thinly sliced, in salads, sandwiches, or as a topping for burgers. For cooking, they can be caramelized to bring out their sweetness, roasted alongside vegetables, or added to stews and curries. Their skins are edible and can be used to add color to stocks. Remember to peel away the outer dry layers before slicing or chopping.
Compared to yellow onions, red onions are generally sweeter and less pungent when raw. Their vibrant color also makes them a popular choice for dishes where visual presentation is important, as they retain their hue even after cooking.
Home cooks and professional chefs alike appreciate red onions for their versatility and flavor.
Store whole red onions in a cool, dry, and dark place, such as a pantry or cupboard. Avoid storing them in plastic bags, as this can trap moisture and lead to spoilage. Once cut, wrap the remaining portion tightly in plastic wrap or place it in an airtight container in the refrigerator.
