Step-by-Step Instructions

Step 1: Prepare the Watermelon

Cut watermelon into cubes and remove any seeds.

For the best slushie texture, place the watermelon cubes in the freezer for 1–2 hours before blending.

Frozen watermelon creates an extra thick, icy drink.

Step 2: Add Ingredients to Blender

Place the following into a high-speed blender:

Watermelon cubes
Ice cubes
Lime juice
Honey (if using)
Mint leaves (if using)

Step 3: Blend Until Smooth

Blend on high speed for:

1–2 minutes

Continue blending until:

Ice is completely crushed
Mixture is smooth
Texture resembles a frozen slush

If the mixture is too thick, add a splash of cold water.

If too thin, add more ice.

Step 4: Taste and Adjust

Taste the slushie.

Depending on your watermelon sweetness, you may wish to add:

More lime juice for tartness
More honey for sweetness

Blend briefly again if adjustments are made.

Step 5: Serve Immediately

Pour into chilled glasses.

Garnish with:

Fresh watermelon wedges
Lime slices
Mint leaves

Serve immediately while icy and refreshing.

Temperature Guide

Ideal Serving Temperature

0°C to 4°C (32°F to 39°F)

The colder the slushie, the better the texture and refreshment.

Tips for the Best Watermelon Slushie

Use Ripe Watermelon

Sweet, ripe watermelon provides the best flavor and may eliminate the need for added sweetener.

Freeze the Watermelon First

Frozen fruit creates a thicker, smoother slushie without watering it down.

Chill Your Glasses

Place serving glasses in the freezer for 10 minutes before serving.

Blend Quickly

Serve immediately after blending to maintain the icy texture.
