If grilling, remove patties and cook on grill until reaching desired internal temperature, flipping halfway through
If using the stovetop, heat a large pan with oil. Add the patties (in batches if necessary) and cook to desired internal temperature. The brown sugar can burn on the stovetop so watch it towards the end and clean between batches if necessary.
