In a large saute pan or cast-iron skillet, cook the onion slices in the olive oil (or chicken fat, if you have some lying around) over medium heat, stirring occasionally, until lightly golden, 5 to 7 minutes. Season with salt and pepper and cook until the onions are caramelized and brown, 3 to 5 minutes longer.

Add 1 sprig each of the thyme, oregano, and rosemary and smash them in with the onions. Deglaze your pan with the port, using a wooden spoon to scrape up the good bits from the bottom of the pan. Cook until all the liquid has evaporated, about 5 minutes. Transfer the onions to a bowl, pulling out the herbs and discarding them, and let cool.

2 minutes on each side. Add the remaining herb sprigs and deglaze the pan with the red wine, scraping up the bits on the bottom of the pan. Cook just until all the liquid has evaporated, about 5 minutes; don't let the livers start to stick to the bottom of the pan. Transfer the livers to a plate or bowl to cool, discarding the herbs.

Toss the cooled livers and onion into a blender (a food processor will also work, but a blender will yield a smoother texture) and turn it on. After the livers have been spinning for about a minute, slowly add the cream and cream cheese and blend to a puree. Taste for seasoning. The mousse should be slightly salty; if it's not, add more salt 1/2 teaspoon at a time. You can add more black pepper too, if you wish.

Pass the blended livers through a fine sieve and pour the mousse into the mold(s) of your choice and chill in the refrigerator for at least 30 minutes before serving. The mousse will keep, covered, in the refrigerator for 1 week.
