* Most dried oregano sold in grocery stores today is the Mediterranean variety, which is grown throughout the Mediterranean region (including Greece, Italy, and Spain) and therefore pairs well with dishes from this region. It will work just fine in this soup recipe, but if you can find it, Mexican oregano adds a more complex flavor that complements the spices in this soup, and in other Mexican dishes, especially well.
** I try to use homemade stock (chicken or vegetable) when making this soup; it really does make a difference in flavor. But, truth be told, sometimes I don’t have any homemade stock on hand, I’m feeling kind of lazy, and I want soup NOW. A good-tasting, all-natural, store-bought broth with recognizable ingredients is a perfectly acceptable substitute. I try to seek out a low-sodium variety so that I can better control the amount of salt in the soup.
*** A note about salt and soup: One of my best tips for making a flavorful soup is to season your soup with kosher salt throughout the cooking process (e.g., when you add the onion, celery, and carrots, then again when you add the rest of the ingredients), not just at the end. Doing so helps to keep your soup from tasting “salty,” rather than properly seasoned. And keep in mind that your stock or broth will likely be salty, so go cautiously. A pinch of salt at each stage is usually enough.
**** To make the
Baked Corn Tortilla Strips: Preheat the oven to 375 degrees F. Working in stacks of 2 or 3 tortillas each, use a sharp knife or pizza cutter to slice
6 (6-inch) corn tortillas in half crosswise, then into thin strips lengthwise, so you end up with strips roughly 2 to 3 inches long and about ½ inch wide. Add the strips to a large bowl and toss them with
1 tablespoon of olive oil and a big pinch of
kosher salt. Arrange the tortilla strips in a single layer on a rimmed baking sheet and bake, stirring once after about 5 minutes, until the strips are lightly golden and crisp, about 10 to 15 minutes. Let cool. (For best results, use fresh, high-quality corn tortillas that are pliable and not too dry.)
