The Difference Between Red, White and Yellow Onions
4- White Onions
At least these onions LOOK a lot more distinct than other onions! White onions tend to have a sharper and more pungent flavor than yellow onions, and they also have a thinner, more papery skin. They can be cooked just like yellow onions, but they’re best minced and added to raw salsas and chutneys.
3- Sweet Onions
Sweet onions are trickier because they look very similar to your average yellow onion. While they may look similar, they taste entirely different than yellow onions do. They lack the sharp, astringent taste of other onions and really do taste sweet.
Typically, these are what you’ll enjoy thinly sliced on top of sandwiches. They can range in color from white to yellow and often have a flattened or squashed appearance. Sweet onions tend to be more perishable than other varieties and should be stored in the refrigerator, unlike their fellow onions.
