How to make a watermelon mule

This watermelon mule has a subtle watermelon flavor, and is a light and refreshing version of a Moscow mule. The concept behind this version of the classic drink is using equal parts ginger beer and watermelon juice, instead of straight ginger beer. This brings in the essence of watermelon and lightens the flavor just a bit. Then, it’s got the traditional ingredients: vodka and lime juice.

Because a mule is all about the carbonation in the ginger beer, this drink is not mixed in a cocktail shaker like our gin & watermelon cocktail and watermelon vodka drink. To preserve the carbonation, it’s simply mixed right in the mug and served over ice.

To make a watermelon mule, you’ll need to start with making watermelon juice: which is very easy using watermelon and a blender! No juicer is required. How to make watermelon juice?

  • Simply cut the watermelon into cubes, then blend it up.
  • When it’s liquid, pass it through a fine mesh strainer to strain out the particulate. Then voila: you’ve got watermelon juice!
  • Note that you’ll get about half the quantity of watermelon juice to cubed watermelon: for example, 2 cups cubed watermelon equals about 1 cup watermelon juice.

In this recipe, we’ve called for the quantities for one drink, because it’s mixed right in the cup. One drink requires only 1/3 cup watermelon juice, but that’s such a small quantity that you’ll want to make more: since you’re probably serving more than one drink at a time! So, scale up the amount of watermelon juice to fit the number of drinks you need.

Does a mule have to be served in a copper cup?

Even if you only dabble in cocktails, you’ll probably know that a Moscow mule is traditionally served in a copper cup or copped mug. But does this watermelon mule have to be served in copper? A purist would say that yes, a mule must be served in a copper cup. One of the reasons is that copper keeps the drink cool in a different way than glass. The copper immediately takes on the temperature of the drink, and the cool copper rim gives a cold sensation when taking a sip.

Probably the most important reason for serving a mule in copper is this: tradition! The drink was invented in the 1940’s, and according to this source, was a clever marketing scheme to sell more vodka, ginger beer, and copper mugs. Whatever the case, people in Hollywood fell in love with the drink and there were many images of people shown drinking Moscow mules out of copper mugs. It caught on, and is popular to this day! (Who needs Instagram to start a trend?)

Of course to us, a mule doesn’t have to be served in copper at all! Whatever glass you use, it will still be a mule. However, it’s just plain fun to serve in the copper! We happened to have some copper mugs on hand, but if you don’t have any, some look alikes are below! (Actually, these are much nicer than ours — and would make great gifts!)
