To score the tomatoes, take a small sharp knife and slice an X across the core. Carefully cut out the core. In a large pot add the chicken broth, tomatoes, onion, dried chiles and bouillon. Bring up to a boil, reduce heat and simmer for 7-8 minutes.
Remove tomatoes from the pot onto a plate and let them cool. Let all ingredients cool for 10 minutes.
After 10 minutes, remove the skins from tomatoes and transfer to the blender. Ladle in the ingredients from the pot, including all of the broth. Add the cloves of garlic, cumin, oregano, pepper and salt to taste. Secure the lid on the blender and blend on high until sauce is very smooth. Straining the sauce is optional. Taste for salt. Set aside.
In that same pot, preheat 1 1/2 tablespoons of pork manteca at medium for 1 minute. Carefully pour in the consomme from the blender. Reduce heat and simmer for 15 minutes. Ladle over your favorite tacos, enchiladas or chiles rellenos.
