If you have the extra time, the extra flavor is worth the effort to saute a small diced red bell pepper, half an onion diced, a diced jalapeño (seeded if you don’t want these too spicy), and a clove of minced garlic. Simply saute until soft and add to the mixture before forming into patties. Still delicious without this step, but better with it in my opinion.
The easiest way to make patties is with these round cookie cutters. If you are using one there is no need to refrigerate the patty mixture. If you aren’t using one, a colder batter will be easier to form into patties using your hands.
