Equipment

Blender

Fine-mesh strainer
Measuring jigger
Cocktail shaker

Tall glass (like a highball or Collins glass)
Knife and cutting board
Small funnel (optional)

Picks for garnishes (optional)

Ingredients

What I Use:

2 cups watermelon cubed
3-4 slices cucumber about ¼-inch thick

2 oz vodka
1 oz fresh lime juice
¾ oz simple syrup

Ice cubes
Optional garnishes:
Extra cucumber slice

Small watermelon wedge
Fresh mint sprig

Instructions

First, I place the watermelon cubes in a blender. I blend until smooth, then pour the puree through a fine mesh strainer into a bowl to remove seeds and pulp.

This step gives a clear juice. Next, I add cucumber slices to the cocktail shaker and press them gently with a muddler.
I pour in 2 oz of the strained watermelon juice, vodka, lime juice, and simple syrup. I fill the shaker halfway with ice, then secure the lid and shake hard for 10–15 seconds.
I strain the mixture into a tall glass filled with ice. To finish, I garnish with a slice of cucumber, a wedge of watermelon, or a mint sprig.

I serve right away for the freshest taste. For a batch, I repeat the steps and scale the amounts.
If I want a non-alcoholic cooler, I skip the vodka and add extra watermelon juice or a splash of sparkling water. It’s honestly just as good that way.

Notes

I make sure to use ripe, chilled watermelon for the best flavor and color. Pre-chilling the fruit means I use less ice, which keeps the drink from getting watery.

I taste the mix before serving and sometimes add extra lime if it tastes too sweet. Tips I follow:

Use fresh lime juice, not bottled, for bright, natural flavor.
If I want more cucumber taste, I muddle extra slices.
For parties, I prepare the watermelon juice ahead and store it in the fridge for up to one day.
If I prefer less sugar, I cut back on the simple syrup or use a sugar substitute.
I often serve this cocktail in summer. It works all year round if quality watermelon is available.

Keeping the presentation simple with fresh garnishes makes the drink look appealing without much extra work. Sometimes, less is more, right?

Tasting Notes

When I take my first sip, I notice the mild sweetness of watermelon right away. The flavor is gentle and not overpowering.

Fresh cucumber adds a crisp edge that feels clean and lively. Flavor Breakdown:

A touch of lime juice gives a hint of tartness. This bit of acidity keeps the drink from tasting too sweet.

I also sense the mint at the end, which adds a cool and soothing finish to each sip. The texture is smooth.

There are no strong bubbles or roughness. I find the drink bright, with clear flavors that blend without covering each other.

If I let the glass sit for a moment, the aromas seem more noticeable. I smell the melon and mint the most, which matches the taste.

The drink stays light, making it easy to enjoy in warm weather. I can’t imagine a better way to cool off.

Substitute

If I don’t have watermelon on hand, I’ll grab honeydew or cantaloupe instead. Both bring in a sweet flavor and keep things looking light.

Pineapple chunks work too, especially when I’m craving a little more tang. Sometimes, that’s exactly what the drink needs.

When I run out of cucumber, I usually reach for zucchini or celery. These swaps keep everything fresh and crisp.

Thin apple slices? They add a whole different kind of brightness, honestly.

If I’m skipping the alcohol, I just leave out the vodka. Sometimes I’ll splash in extra fruit juice, sparkling water, or even a flavored seltzer if I’m feeling fancy and want a fizzy twist.

For sweetener, agave, maple syrup, or just plain sugar all work. I kind of just go with whatever’s in the pantry and tweak the flavor to fit my mood.

Fresh herbs like basil or mint really brighten things up. If mint’s missing, I’ll toss in lemon balm, or—if I’m feeling adventurous—a tiny bit of cilantro for a different kick.
