I am planning an indoor party for this weekend and I would like to serve around 100 sliders. I will not be able to grill during the party and would rather not cook on the stovetop. I have found a few articles suggesting that burgers could be pre-grilled and kept warm and juicy by either storing in a steamer on the stove or in a pot in the oven. In both cases beef broth is used as the liquid. Has anyone tried this before? Do you end up with uber well done burgers? Any other suggestions?
