This Sopa Azteca is one of the best things I have ever made for myself. Unlike a traditional tomato soup, it is very thin and perfect for Level 0: Thin. I modified this amazing Sopa Azteca from Farideh Sadeghin’s Mexican Tortilla Soup (Sopa Azteca) posted on saveur.com.
I discovered this type of tortilla soup at a restaurant here in Tucson – BK Tacos. Tucsonans have strong opinions about BK’s, but I am heartily in the “for” category. Their “Sopa de Tortilla” absolutely blew my mind the first time I tried it. If you’re anything like me, you expect a tortilla soup to be either basically a chicken chili or a creamy, yellow-orange glob. This thin, spicy, tomato soup is served with avocado and soft, fresh cheese as well as strips of tortilla and lime wedges.
I originally attempted to create a Level 1: Slightly Thick by blending the traditional toppings into the soup base. This was delicious – but it never thickened up enough for a Level 1. This is why we test before we serve! Luckily for us Level 0 lovers, this means that you can add a fair number of toppings and stay nice and thin (just remember to test!).
I love to serve this soup to my friends with the toppings “family-style” in the middle. I typically also stir this up a little less spicy and leave the hot sauce on the table. Some of my friends have more sensitive gastrointestinal tracts, for them, I dish out a few servings of soup before I add any hot sauce and warm it up again when they arrive.
The absolute best hot sauce to use for this is the spiciest sauce from your neighborhood taco shop: we’ve added the sauce from BK’s, the Taco Shop, and Coronado’s Mexican Food to different versions of this soup. Of course, you can use whatever you prefer and have on hand. Sriracha works fine, as well as Tapatio and Tabasco.
The original recipe I modified called for pasilla chiles. I couldn’t find these in my grocery store, so I’ve used “chiles negros.” I probably could have gone to a carniceria, but I have such a hard time pronouncing that word that I never want to ask Josh to take me.
The most stressful part of this recipe for me is toasting the chiles. It’s really not hard, you just put the chiles in the pot – I just get nervous that I’m going to burn my fingers. After toasting, you’ll need to stem and seed the chiles. I have Josh do this for me because I am cursed with Hot Pepper Hands. If he’s not home, I put Ziploc bags on my hands and just rip the chiles to pieces (no shame). If you end up with Hot Pepper Hands, I’m sorry. Alternating washing your hands in dish soap and vegetable oil works best for me.
After I blended my chiles, tomatoes, garlic, and onion together I had to run it through a sieve. If you have an incredibly powerful blender that can break up those tomato seeds, you may not need to. As you can see, I had quite a bit of *flavor* that I had to remove because of chunkiness.
This soup is a delicious and amazing addition to your Level 0: Thin eater’s diet as well as to your entire family and friends. Always remember to test before you serve!
