Step 1: Make the Blueberry Base

Place 2 cups of fresh blueberries, ½ cup sugar, and ¼ teaspoon salt in a medium saucepan.

Add 1 cup of water and bring the mixture to a boil over medium-high heat.

Once boiling, reduce the heat and simmer for 5 minutes, stirring occasionally, until blueberries begin to break down and the sugar dissolves completely.

Blend the Mixture

Remove the saucepan from heat.

Carefully transfer the blueberry mixture to a blender.

Blend on high until the mixture is completely smooth (about 30 seconds to 1 minute).

Tip: Let the mixture cool slightly if your blender isn’t heat-safe.

Strain for Smoothness (Optional)

Pour the blended blueberry mixture through a fine-mesh strainer into a large pitcher to remove pulp and seeds, if desired.

Use the back of a spoon to help press the liquid through.

Add Lemon and Water

Stir in 1 cup fresh-squeezed lemon juice and the remaining 3 cups of water.

Mix until well combined.

Taste and adjust with more sugar or lemon juice, depending on your preference.

Chill and Serve

Refrigerate for at least 1 hour before serving, or until thoroughly chilled.

Serve over ice, garnished with extra blueberries, lemon slices, or fresh mint, if desired.
