Finely chop onions. Wrap onions in a clean towel and squeeze out excess moisture. Add ground pork to a medium mixing bowl with onions, garlic, maple syrup and spices. Mix together well, cover and store in the refrigerator for 4 - 24 hours.
Form into patties, and cook in a pre-heated skillet over medium heat until done. Approximately 3-4 minutes per side.
This recipe freezes incredibly well, raw and cooked. So go ahead double or triple the batch and have extra for later!
