I added 4-6 jalapenos and blended them with the guajillos, 1 large tomato which I blended with the peppers, added 1/2 extra tsp cumin, 1/2 extra tsp chili powder, 3 tbsp brown sugar, 1 tsp ghost pepper powder, and 2 tbsp of apple cider vinegar to get the flavor I wanted. I prefer bolder sauces, broths, so I added the above to taste. Turned out really well.
