The Tortilla Soup Ingredient That Should Be Kept Raw
Tortilla soup is a Mexican favorite that consists of chicken broth, roasted tomatoes, onion, garlic, chiles, and possibly more, topped off with corn tortillas that are cut into strips and fried. When making soup, most of us are inclined to soften and brown our aromatics, including onions, but this is a big "no" for traditional tortilla soup.
According to the Los Angeles Times, when making tortilla soup, there's no need to cook the chopped white onions; you can just leave them raw. Mexican cooking authority Diana Kennedy told the Times, "To be really authentic, the soup should have only a little white onion, raw not cooked, blended with roasted tomato."
Mexican Please explain that raw white onions have a sharp taste to them and can really make the flavor of foods pop. You may need to use a little effort to properly blend the onions with the tomatoes, but you do get to skip the extra step of cooking the onions before adding the other soup ingredients.
