Which Onion Type To Use

The recipe your making lists "onion" in the ingredients, but which type do you use?

Unless the recipe lists a specific type by color or name, opt for a standard yellow onion.  Yellow onions are tasty, cheap, and versatile; and tend to be neither too sharp nor too sweet.

Notes on a few other varieties:

Spanish:  Spanish onions tend to be very large, thought their flavor is similar to yellow onions.  Because this variety is so big, it isn't usually a practical choice for home cooking.  Though if you are hosting a cookout or making an onion blossom, these could be a good choice.

Red:  Red onions tend to be sweeter than yellow onions, and they add a nice pop of color to dishes you use them in, especially salads.

White:  White onions are more pungent (i.e. likely to make you cry as you are cutting them) and have a fuller flavor than yellow onions.  Depending on your taste preference, you can often interchange white and yellow onions without any problem.

Mmm...tasty!
