I too love the idea of a slider. And I agree that neither Krystal Burger or White Castle taste good unless you are very drunk and, even then that's debatable. Eating either companies burgers probably will result in an extended stay on the throne the next day. I try to make my version of a slider whenever the urge for a burger hits. I don't really care what ingredients are traditional on a slider, I just add what tastes good to me. That said I can get a little anal-retentaive about condiments and toppings. The mayo, mustard, and ketchup I use are all homemade. I usually bake my own slider buns but, having lived in PA for a few years I can vouch for the quality of Martins potato rolls and would use them if they were readily available where I live. I always grind the meat myself. Usually beef chuck, but the most recent batch was boneless beef short rib and it worked nicely. Add some diced onion sauteed with the beef, cheese, and shredded lettuce and that's enough to satisfy me. It might seem a lot of work to make a mini-burger but the resulting product is delicious and worth it every second it takes. As a bonus your stomach won't punish you the next day. -Mark
