I don't like burgers that have a ton of unidentifiable ingredients in them so I decided to keep this one simple. It works perfect for any condiment or topping. My favorite burger is the Rodeo Burger from Buzz Inn in Washington so I felt this would work well with those toppings. Sauteed onions, crispy bacon, barbeque sauce, and cheese. This kept everyone guessing about what was in them because they do keep very moist and at the end of the night as everyone was leaving, I couldn't even count how many people said The hamburgers were great as they said good night and thanked us for dinner. I work the meat for a while and sprinkle the salt over just a little at a time so it gets distributed and I know for sure that there isn't a huge salt pocket that will get stuck in one of the patties. Sorry, I don't actually know serving size because we didn't even use all the meat up and patties size will differ; freeze unused meat for later if it hasn't been thawed.
