Red onion facts & tips
Opt for onions that are firm and have a bright, smooth outer skin. They have a milder, sweeter flavor.
Store red onions in a cool, dry, well-ventilated place, away from potatoes. They can last for several weeks to a few months. Once cut, wrap tightly and refrigerate, using within a few days.
