These Spanish onions were for sale at the Newark, Delaware farmer's market.

I am not exactly clear what distinguishes Spanish onions from yellow onions in general, or if they are just different names for the same variety. However, I buy these onions regularly: they are staple in my house. I find them similar in flavor to red onions, but they often seem to keep slightly longer. They are not sweet onions, but are not quite as harsh as white onions.
