Final answer:
To cook a Junior patty and maintain its shape, cook it on medium-high heat for 3 to 4 minutes on the first side until golden brown, then flip and cook the other side for an additional 3 to 4 minutes.
Step-by-step explanation:
To cook a Junior patty and ensure it holds its shape, the key is to cook it evenly and not flip it too early. Start by heating your pan or grill to a medium-high temperature and lightly oil it if necessary. Place the patty on the hot surface and cook it undisturbed for about 3 to 4 minutes on the first side. This initial sear helps in creating a crust which keeps the patty together. Resist the urge to press down on the patty with your spatula, as this can cause it to lose its juices and fall apart. After the first side is cooked to a golden brown, gently flip the patty to cook the other side until it reaches the desired doneness, usually another 3 to 4 minutes for a medium-cooked burger. Remember, cooking times can vary based on the thickness of the patty and the heat of the cooking surface.
