A glossy, bright orange pan sauce for pork tenderloin — fresh orange juice and zest reduced with shallot and a splash of orange liqueur, finished with cold butter so it shines and clings. It comes together in the pan while the pork rests.
Made for pork tenderloin, but it's just as good over pork chops, chicken breast, or even duck — anything mild that likes a sweet-tart citrus sauce.
The orange liqueur is worth it. A tablespoon of Grand Marnier or Cointreau deepens the orange and rounds the edges, but the sauce is lovely without it.
Don't let it break. Cold butter whisked in off the heat is what makes it glossy and emulsified; boiling it after the butter goes in can turn it greasy.
Zest first, then juice — and take only the orange part, not the bitter white pith (a fine zester makes it easy).
Gluten-free: naturally — just use a gluten-free stock.
Dairy-free: finish with a spoon of olive oil instead of the cold butter (a little less glossy, still good).
Vegetarian: use vegetable stock and spoon it over roasted squash, tofu, or seared mushrooms.
