For optimal onion flavor and texture, consider a slower, longer caramelization process for the onions before adding balsamic vinegar, enhancing their natural sweetness and depth. When cooking extra-lean ground beef, be mindful not to overcook the patties to prevent them from drying out; the specified 160°F (71°C) is a safe internal temperature. The use of a heavy skillet to press the sandwiches is crucial for achieving a beautifully crisp rye crust and ensuring the cheese melts thoroughly and binds all layers. For an even richer result, consider brushing the exterior of the rye bread with melted butter or a butter-oil blend before toasting.
