Red onions are a sweet onion with a pleasing purple-red coloration.
Choose an onion based on its skin. It should be shiny with very thin skin, almost like a tissue. The pointy end of the onion should be dry and compact. Avoid any with signs of decay or wetness. They can be stored in a cool, dry place for up to three weeks.
Red onions need to have their outer layer peeled first. They are commonly used in salads. You can also simmer them to get some caramelization out of them. Red onions are a great addition to any meat dish. The sweetness of the onions compliments pork chops nicely.
