I really could not believe how close these come to real "live" White Castle burgers. I have only a few changes though. This recipe said make the meat about 1/2 inch thick, it needs to be even flatter. This is an excellent recipe for making burger really cheap. For one pound of beef use about 1.5 to 2 tablespoons of the soup mix. You will also need dried chopped onions (soak them in hot water for about 12mins, then drain well). Fresh onions just don't have that same flavor. You may have to cook it a few extra minutes to get it done. What I do is after it is cooked, I cut into squares using a pizza cutter and using a bun as a guide for the measurements. A 9x13 you could cut into 3 lenghtwise 6 or so in the other directions, but use you own judgement. Then I drain them well on paper towels then put them on foil and let them cook an additional minute or two (I don't like grease at all, lol). You can sprinkle the rolls as directed but I put them in the micro for about 20 seconds. White Castle burger rolls are never toasted, but steamed. These are very good burgers.BTW, I used to eat about 15 white castles at a time. So when I say these are close.......they are really close.
