1. Fry the frozen hamburger patties for 4 minutes on each side.

2. If the time is too short, it will be too raw. If the time is too long, the patty will become old and affect the taste. Generally, it depends on the color and is fried until golden brown on both sides. The same goes for the choice of beef for burgers. It is very particular. The meat near the back is the most tender, and the meat in the sirloin is the most tender because it has less movement. Using these two parts of meat to make meatloaf has the best taste.
