Notes
The directions above build the mule in the mug. But, you can also build this in a shaker and shake to mix.
Also fill the shaker with ice.
Measure ingredients directly to the shaker.
Cover the shaker with it's lid.
Shake well for about 15 seconds; not too vigorously so the gingerbeer doesn't fizz.
Remove the lid.
Add the strainer on top of the shaker and pour into the mug.
add mint leaves or cranberries if garnish is desired.
