A simple recipe for a classic rum cocktail.
Unless it is excessively dirty, there is no need to peel the ginger prior to grating it.
When I make these for a crowd, I grate the ginger on a box grater rather than a microplane to make it go faster; alternately, you can put the ginger through a juicer.
Gosling's Black Seal rum is the one to use if you can get it (BevMo is a good bet); its flavor is unparalleled. But it will still be tasty with The Kraken or Meyers.
I've been told that a shot is anywhere from 1 1/2 - 3 ounces by volume. Being a lightweight, I keep these on the demure side so that I won't drink myself under the table (or end up dancing on top of it). But feel free to make 'em stronger if you like! More rum may necessitate more agave.
