Onions

Look: Dry, papery skins with a tight, small neck and no green sprout poking from the top.
Feel: Rock hard through the shoulders — any softness at the neck means rot is starting inside.
Smell: Mild and faintly sweet through the skin; a strong oniony or musty smell signals a bruised or rotting bulb.
Tip: For sweets like Vidalias, pick the flattest bulbs on the table — the flatter the disc, the milder the bite.
Keeps: Cool, dark, dry pantry — storage types keep for months, sweet onions only a few weeks.
