In a small bowl, stir together salt and peppers. Rub mixture on both sides of pork chops.
In another small bowl, whisk together satsuma juice, honey, mustard, and vinegar.
In a 12-inch cast-iron skillet, melt 1 tablespoon butter over medium-high heat. Add pork; cook until browned, about 2 minutes per side. Pour juice mixture onto pork; add shallots and thyme.
Bake until an instant-read thermometer inserted into thickest portion of pork registers 145°, about 5 minutes. Transfer pork and shallots to a serving platter, and keep warm.
Return skillet to medium-high heat; cook until skillet juices have reduced and thickened, about 3 minutes. Stir in remaining 1 tablespoon butter. Drizzle sauce onto pork. Garnish with satsuma zest and thyme, if desired.
