How to Make It
Wash the scallions in two or three changes of cold water. Slice them crosswise into 1/2-inch pieces.
Using a meat pounder, lightly pound the pork scallops to a 1/4-inch thickness.
Put the oil and 1 tablespoon of the butter in a large skillet and turn the heat to high. When the oil is hot, lightly flour the pork scallops and add them to the pan. Brown them well on both sides, then transfer to a warm plate.
Reduce the heat to moderately low and add the scallions to the skillet. Season with salt and pepper, cover and cook, stirring from time to time, until the scallions are very, very soft about 20 minutes. Stir in the capers and the remaining 1 tablespoon of butter.
Return the meat to the pan and season with salt and pepper. Cook over moderate heat just until the meat is warmed through, turning it over once or twice. Turn the contents of the skillet out onto a warm serving platter and bring to the table at once.
