Ingredients

• 6 cups seedless watermelon cubes

• 1 to 2 tablespoons honey, agave, or sugar
• 1 cup ice, for serving
• Lime slices, for garnish
• Fresh mint, optional

Ingredient Notes

Watermelon

Use ripe seedless watermelon for the sweetest flavor and smoothest drink.

A good watermelon should feel heavy for its size and have a creamy yellow field spot.

Water

Cold filtered water gives the drink a clean, fresh taste.

Start with less water if your watermelon is very juicy, then adjust after blending.

Lime Juice

Fresh lime juice adds brightness and balances the sweetness.

Lemon juice can work, but lime gives a more classic agua fresca flavor.

Sweetener

Honey, agave, or sugar all work.

If your watermelon is very sweet, you may not need much sweetener at all.

Mint

Mint is optional, but it gives the drink a fresh summer finish.

How to Make Watermelon Agua Fresca

1. Cut the Watermelon

Cut the watermelon into cubes and remove any seeds.

Chill the watermelon first if you want an extra-cold drink.

2. Blend

Add the watermelon cubes, cold water, lime juice, and sweetener to a blender.

Blend until completely smooth.

3. Strain

Pour the mixture through a fine mesh strainer into a large pitcher.

This step gives the agua fresca a smoother, lighter texture.

If you prefer a thicker drink, you can skip straining.

4. Taste and Adjust

Taste the drink and adjust with more lime juice, sweetener, or water.

The flavor should be lightly sweet, fresh, and balanced.

5. Chill

Refrigerate for at least 30 minutes before serving.

This helps the flavors settle and makes the drink extra refreshing.

6. Serve

Pour over ice.

Garnish with lime slices, watermelon wedges, and fresh mint if desired.

Expert Tips

Use Cold Watermelon

Cold watermelon makes the drink more refreshing and reduces the need for extra ice.

Strain for Smoothness

Straining removes pulp and creates the light texture agua fresca is known for.

Adjust Sweetness Last

Watermelons vary a lot, so taste before adding extra sweetener.

Serve Over Ice

Add ice to the glasses, not the pitcher, so the drink does not become diluted.

Stir Before Serving

Natural watermelon juice can settle, so stir the pitcher before pouring.

Easy Variations

Watermelon Mint Agua Fresca

Blend a few mint leaves with the watermelon.

Strawberry Watermelon Agua Fresca

Add 1 cup fresh strawberries for a berry version.

Sparkling Watermelon Agua Fresca

Replace 1 cup of water with sparkling water right before serving.

Spicy Watermelon Agua Fresca

Add a tiny pinch of Tajín or chili lime seasoning to each glass.

Cucumber Watermelon Agua Fresca

Blend in ½ cup peeled cucumber for an extra refreshing twist.

Storage

Store watermelon agua fresca in a covered pitcher in the refrigerator for up to 3 days.

For best flavor, serve within the first 24 to 48 hours.
