The patties tend to crisp up more on the outside than the middle. To make the middle crispier, make a finger sized hole in the patty, similar to a donut, then batter and fry them as directed. This will help the middle get crunchy.
You can also crisp up the patties by frying them for 2 minutes on each side, then baking them at 350 F for about 20 minutes.
