Red Onion
Look for a red onion that:
- Is firm and feels heavy in the hand for its size
- Has a dry, somewhat tough, and deep purple outer skin
- Is dry and free of bruises and soft or dark powdery spots
- Has little or no smell
- Has a tightly-closed neck with no signs of sprouting
As long as it remains dry and does not have dark powdery spots, a red onion does not need to perfectly meet all the criteria above to be edible or usable in a recipe. The closer it is to meeting these guidelines, however, the higher its quality should be.
Notes
Red onions have a strong, slightly sweet flavor and are well-suited for eating raw. They are typically used on burgers, in salads, salsas, for pickling, and other recipes that call for raw onions. One medium-sized red onion should yield three-fourths to one cup of chopped onion.
After you get your red onions home
Onions should be stored in a dry environment with good air circulation, and typically will last up to two weeks when stored at room temperature. Keep your onions in an open paper bag, net bag, or material that promotes good air circulation. If you want to store your onions in the crispier of your refrigerator, wrap them in a paper towel to absorb moisture. Because onions have quite a bit of moisture content and are susceptible to bruising, mold, and rot, they should never be wrapped in plastic or stored in airtight containers.
