This is the quickest and easiest way I've found to make juicy, yummy burgers. I actually make the wine glaze ahead of time and just keep it in the fridge, that way I can easily make one or two burgers without too much hassle! However, be careful in the amount you use: although the proportions in this recipe are fine, I found they don't scale down exactly, so use a bit less of the glaze if you're just making 1 or 2 burgers (i.e. don't just use one quarter or one half of what the recipe says).
