How do you sweeten onions?

Answer 1

It is by lowering sulfur and raising water contents that onions are sweetened for cultivation and by chilling, heating or soakingthat they are sweetened for serving.

Specifically, sweet onions are big and round because of their water content. They are not pungent because they are grown from carefully selected, fresh seed from the season's sweet onions. But they do not have to be alone in their sweet taste since other onions provide less pungent tastes after chilling in ice, heating in a pan of oil or on a grill, and soaking in cream or milk.
