Forgot to defrost the butter? @&%$!

Okay, so you are a dupa (boludo, in Spanish, in Argentina), like I was, and forgot to remove the butter from the refrigerator (or freezer) to bring it to room temperature.  If you going to mix the butter for cake, there is a simple solution that will immediately bring your butter to room temperature:  Simply grate it.  Instant gratification!

Note: if you don’t have a grater, I imagine that a vegetable peeler would work too.
