It’s the state vegetable of Georgia.

“Vidalia onions aren’t just the most famous onions in the world; I think they may be the only famous onions in the world.”
Chef Bobby Flay

They are so mild, I’ve seen people eat them like apples.

They come from Vidalia, Georgia, and the sweetness is said to be a by-product of the low sulfur in the soil.

Slice them thick, bread them and fry them and they make the most delicious onion rings ever.

Vidalia Girl,
won’t you tell me why
Sweet Vidalia
You always gotta make me cry
Sammy Kershaw – Vidalia Lyrics | MetroLyrics
