A different onion type won't spoil the recipe

Q: So many recipes call for yellow onions. But there also are white onions, sweet onions and red onions. Does it really matter if a recipe specifies a yellow onion and you use one of the others?

It does seem like there's an endless variety of onions. And since they each taste a little different, we can vary recipes by changing whether we use a scallion or a shallot.

Still, they are all onions. As long as the onion is the same basic type, such as a bulb onion, the results will be similar. A red onion may be more intense than a white onion, but the recipe will work with either one.

However, one big advantage to the yellow onion is price. Yellow onions are usually much cheaper than sweet onions or red onions, which is why so many recipes use them as kitchen workhorses.
