12 oz. Cold Beer
1/2 Mexican Lime or Key Lime (same thing as far as I know)
Open a can or bottle of your favorite bad beer. Tecate is sufficiently bad but you don't really have to pay that much. The lime and salt do the work. It has been rumored that this recipe may even work with Keystone Light. In fact, it may be the only way to save that patient.
Pour the beer into a glass, or leave it in the container, then squeeze half a lime into the beer. Then salt to taste, but don't take too much time with this step because you may lose half your beer as it foams over the top if you dawdle.
If you are sharing this experience with a friend, it can be quite a trick to get both of your beers prepped in time to exchange a toast of "Cheers", "Salud", "Ciao", or "Here's to (whatever.)" Two salt shakers can solve this problem. In any event, the toast must not be dispensed with. A can works well because you get that pre-beer blast of straight lime and salt that has collected around the top, which is nice. But if you don't want to be reminded of what beer you had to settle for, or that you're drinking from a can, then go for the glass.
At this point, Ben Franklin's adage will come to mind: "Beer is proof that God loves us and wants us to be happy."
