What country does a spanish onion come from?

While the name "Spanish onion" might lead you to believe it originated in Spain, it's actually a misnomer. There's no specific country of origin for Spanish onions.

The term "Spanish onion" is often used to describe a type of yellow onion that is mild and sweet, with a slightly elongated shape. It's likely the name arose from the fact that Spain was a significant importer of onions in the past, or perhaps because some varieties of yellow onions were cultivated in Spain.

So, while it's not a Spanish onion specifically, it's generally a yellow onion that's known for its mild and sweet flavor.
