Pounding poultry to an even quarter-inch thickness requires consistent downward force rather than glancing blows, preventing premature holes that allow cheese fillings to leak into hot oil. Double-layering plastic wrap around each breast keeps the delicate muscle fibers intact while flattening uneven lobes. Mounding the filling tightly down the center leaves a one-inch bare margin on all sides, ensuring the protein seals securely around the spinach and cheese core without bursting open during the initial two-minute sear.
Combining white wine and chicken stock in a non-reactive pan prevents metallic off-flavors from dissolving into the liquid during reduction. Boiling the mixture rapidly evaporates water content until it coats the back of a spoon, concentrating the foundation before Dijon mustard and fresh lemon juice are whisked in off the heat to prevent curdling. Scraping the skillet with a wooden spoon after searing the poultry incorporates browned fond into the finishing liquid, adding savory depth to the bright citrus notes.
Refrigerated medallions retain moisture for up to two days when stored in an airtight container separate from remaining sauce. Reheating requires gentle, low-temperature oven warming rather than microwave exposure to prevent the chicken protein from toughening and the gorgonzola fat from separating.
