I have only 'cooked' this in my head. Adjustments might be needed. Again, I have no idea what the sauce you had consisted of but this should at least give you a starting point. Criticize at will and I can help you figure out any problems or adjustments.
3 dried ancho chiles
1 onion, half of it minced, half of it diced
1 tablespoon rendered bacon fat (drippings); strained
1 small tomato, peeled, seeded and chopped
1/2 canned chipotle chile in adobo
3/4 cup oil-packed sun-dried tomatoes, drained and finely chopped, oil reserved
2 cloves garlic, minced or pressed
1/4 teaspoon dried rubbed sage
pinch cumin
pinch cinnamon
2 cups low-salt chicken stock, or 1 can of same, plus another cup of so, if needed
salt
white pepper
couple pinches sugar
honey
apple cider vinegar
Soak ancho peppers in very hot water for 25 minutes, plate-weighted to keep them submerged; drain well; remove stems and seeds; chop.
Heat a medium skillet on medium-high heat. Add the bacon fat. Sauté chopped chiles, the chipotle and the diced half of the onion in the pan until tender, about 7-8 minutes. Add the chopped tomato and cook a couple minutes longer till softened. Remove from the heat and allow to cool slightly. Purée this mixture, adding a little of the stock as you go - enough to help the purée occur - till very smooth. Force through a strainer into a bowl; discard solids in the strainer; reserve.
Wipe out the pan and reheat it. Add a tablespoon of the reserve oil from the sun-dried tomatoes. Add the minced half of the onion and cook 2 minutes. Add the sun-dried tomatoes and cook 4 minutes more. Add a splash of the stock (maybe a couple tablespoons), the sage, cinnamon, cumin, and a little white pepper, and cook till the stock has reduced to nothing and the dried tomatoes are quite tender. Add the garlic and cook till very fragrant, stirring, about 45 seconds.
Add the reserved ancho purée to the pan and bring to a strong simmer. Reduce the heat to low and simmer gently for several minutes, 7 or so anyway. If the sauce over-reduces add a little more stock to restore consistency. Add the couple pinches of sugar and stir well allowing to dissolve completely. Taste and adjust salt. Adjust pepper.
Remove the sauce from the heat and add a little honey, a teaspoon at a time, till just slightly flavored. Reserve, keeping warm, covered, till service.
