I kind of like the texture of store bought patties. When I make my patties, they seem to be more dense and packed together than I prefer. I coarse grind once now. I was coarse grinding and then moving to the next less coarse grind plate. I grind once, add my spices. I have also been adding non-fat dry milk as a binder. Then I use a press to mash out my patties. Is my press compressing to much? Do I need to add the binder? Any info is appreciated. Thanks.
