Why can't the burger patty be evened out more than once?

The burger patty should not be evened out more than once primarily because doing so can remove too much juice from the patty. When a patty is pressed down too forcefully or frequently, it expels the flavorful juices that keep the meat moist and succulent during cooking. This loss of moisture can lead to a drier, less enjoyable burger, as the juices are essential for flavor and texture.

Additionally, while other factors like flavor alteration, cooking time, and appearance are relevant considerations in burger preparation, the critical concern revolves around maintaining the juiciness and integrity of the patty. Ensuring that the burger retains its natural juices is fundamental to achieving the best possible taste and experience for diners.
