Choosing the Best Watermelon

A creamy yellow field spot
Deep green skin

A hollow sound when tapped

Avoid watermelons with:

Soft spots
Deep cracks
Bruises
Dry or shriveled stems

Step 1: Prepare the Watermelon

Wash the outside of the watermelon thoroughly.

Cut it in half and then into quarters.

Carefully remove the rind.

Slice the flesh into cubes.

Remove any visible seeds.

Measure approximately eight cups of watermelon cubes.

Place them into a large bowl.

Using cold watermelon creates an even more refreshing drink.

Step 2: Prepare the Remaining Ingredients

Peel and chop the cucumber.

Wash the mint leaves.

Roll the lemons firmly on the countertop before juicing to release more juice.

Cut the lemons in half.

Juice them and remove any seeds.

Measure the honey and rose water if using.

Prepare all ingredients before blending.

Step 3: Blend the Cooler

Place the following into a blender:

Watermelon cubes
Chopped cucumber
Mint leaves
Fresh lemon juice
Cold water
Honey
Pink salt

Blend on high speed for 2 to 3 minutes until completely smooth.

The mixture should become frothy with a bright ruby-red color.

Step 4: Strain the Mixture

For a smoother beverage, place a fine mesh strainer over a large pitcher.

Slowly pour the blended mixture through the strainer.

Use the back of a spoon to gently press the pulp.

Continue until most of the liquid has passed through.

Discard the remaining pulp or save it for smoothies, frozen treats, or fruit sauces.

If you enjoy a thicker drink, simply skip this step.

Step 5: Add Rose Water

Stir the rose water into the strained juice.

Only a small amount is needed.

It provides a gentle floral aroma that complements the watermelon without overpowering it.

This ingredient is optional but adds an elegant finishing touch.

Step 6: Chill the Cooler

Cover the pitcher.

Refrigerate for 30 to 60 minutes.

During chilling, the flavors become more balanced.

The mint becomes more fragrant, while the citrus blends beautifully with the watermelon.

Step 7: Prepare the Glasses

Fill serving glasses with plenty of ice cubes.

For an attractive presentation, add:

One lemon slice
One cucumber ribbon
A few watermelon cubes

The colorful garnishes make the drink look festive and inviting.

Step 8: Serve

Pour the chilled watermelon cooler over the ice.

Top with:

Fresh mint sprigs
Watermelon wedges
Lemon slices
