Instructions
Step 1: Muddle or Blend the Watermelon
Add fresh, seedless watermelon chunks into a cocktail shaker or small blender. Muddle until the fruit breaks down completely into juice. If you prefer a smoother texture, strain through a fine mesh strainer.
Step 2: Add Vodka and Lime Juice
Pour in 2 oz of vodka and ½ oz of fresh lime juice. These add crispness and balance to the watermelon’s natural sweetness.
Step 3: Shake or Stir
Add a handful of ice to the shaker. Shake briefly just to chill and mix. If using a glass, just stir well.
Step 4: Fill Your Mug or Glass
Fill your copper mug or tall glass with ice. Strain the watermelon mixture over the ice.
Step 5: Top with Ginger Beer
Slowly pour 3–4 oz of ginger beer over the mix. It adds fizz and that signature mule spice that pairs beautifully with watermelon.
Step 6: Garnish and Serve
Garnish with a fresh wedge of watermelon, a sprig of mint, or a slice of lime. Serve immediately and enjoy chilled.

FAQs
Q1: Can I use store-bought watermelon juice?
Yes! Just make sure it’s 100% juice with no added sugar. But fresh watermelon gives the best flavor and texture.
Q2: What if I don’t have a shaker?
No problem. You can muddle the watermelon directly in a glass, mix it with the other ingredients, and stir well.
Q3: Can I make this ahead of time?
You can prep the watermelon, vodka, and lime mix a few hours in advance. But always add ginger beer fresh to preserve the fizz.
Q4: What kind of ginger beer is best?
Look for spicy and bold varieties like Fever-Tree or Reed’s for more kick. For a milder taste, go with lighter brands.
Q5: Can I make it non-alcoholic?
Absolutely. Skip the vodka and replace it with sparkling water or more ginger beer for a Watermelon Mule mocktail.
