Stove Top Instructions
Season the meat as in the recipe then brown it in the oil in a Dutch oven.
Add the broth, onion, celery, guijillo chile, and garlic. Simmer, covered, on low heat for about 1-1/2 hours on top of the stove.
Cook the noodles as directed in the recipe.
You can thicken the gravy by pouring it into a saucepan and stirring in 2 tablespoons of cornstarch that has been blended with 1/4 cup cold water. Simmer until thick.More Tips
Browning the meat gives it a more robust flavor and adds some texture. You can skip that step if you must but I don't recommend it. Without the browning step the recipe is pretty average. Once you brown that beef though - WOW.
I add part of the beef broth to the water I cook the egg noodles in because it gives them that "second day" flavor. You know, things like this are always better on the second day because they've had time for the flavors to blend? Well this speeds that process up.
It's not in the recipe but add a whole carrot to the meat while it's cooking and fish it out (or mash it into the gravy) before serving. The carrot adds sweetness and a little nutritional boost to the dish.
