Two 3/4-pound pork tenderloins, each cut crosswise into 4 pieces and pounded 1 inch thick
Salt and freshly ground pepper
2 tablespoons unsalted butter
1 shallot, minced
3/4 cup chicken stock or low-sodium broth
2 tablespoons strawberry jam or preserves
Scant 1 teaspoon chopped thyme
1 teaspoon Dijon mustard
In a large skillet, heat the oil. Season the pork with salt and pepper; cook over high heat, turning once, until browned and just cooked through; transfer to a plate and cover loosely with foil.
Melt 1 tablespoon of the butter in the skillet. Add the shallot and cook over moderate heat, stirring, until softened. Add the stock, jam and thyme; cook over high heat, stirring until thickened.
