Chicken or Beef Stock
Chicken or Beef Stock is a meat ingredient where cut size, trim, and surface moisture matter. Keep the pieces dry for browning, cook to the texture the dish needs, and season with control.

Why It Works
Cutting the potatoes into thick discs with two flat sides makes them easy to brown and then braise in a skillet. Fortifying stock with gelatin turns the braising liquid into a rich sauce. Finishing the dish in the oven helps to produce fondant potatoes' characteristic "melting" tenderness.
