Onion is a vegetable in the Allium genus, which includes garlic and chives. For more than 5,000 years, this distance cousin to amaryllis has been cultivated as a food crop.
Most people have experienced tearing from chopping a raw onion, which is caused by a reaction between alliinase enzymes in the vegetable and oxygen in the air. Using dried, chopped onion not only eliminates this response, but also has the added benefit of an extended shelf life.
