How do you choose which onion to use?
I tend to gravitate toward buying sweet onions like vidalias or walla wallas, but I think I remember reading that they have more water than yellow onions. I don't know what's right.
I use red onions to pickle or in salads.
I use white onions when I'm cooking Mexican because that's what Mexican recipes usually call for.
Looking for guidance here from my more knowledgable friends.
