6 small shallots , peeled (and halved if large)
2 cups apple cider - I substitute 1 cup boiled cider from King Arthur Flour for the cider
1/2 cup apple butter
1 bay leaf
1 sprig fresh thyme
1 teaspoon cider vinegar
cook 1 tablespoon oil and shallots in empty skillet over medium heat until golden brown, 3 to 5 minutes. Increase heat to high, add cider, apple butter, bay leaf, and thyme and bring to boil. Cook until thickened, about 8 minutes.
Start roast with fat side down at 375 deg. After about 25 min spoon glaze over loin. Roll loin and spoon on more glaze. Cook until internal temp is 145 deg spooning on more glaze 1 or 2 more times.
When done, remove loin from heat and tent for about 20 min on cutting board.
Transfer glaze to small saucepan and whisk in vinegar. Spoon over sliced meat on platter and/or serve table side.
