Step 1

Blend: Add the blueberries, lemon juice, sugar, and salt to the base of a large blender. Cover with cold water, seal well, and blend on high for 30 to 45 seconds, until smooth (Note: if you have a smaller blender, use only 2 cups of water, then add the rest of the water to the pitcher in step 2 after straining)

Step 2

Strain: Fill a pitcher with ice, then strain the blueberry liquid into the pitcher using either a fine mesh strainer or a nut milk bag. Both will remove the blueberry skins and seeds, but the nut milk bag does have a slightly smoother texture and is what I recommend!

Step 3

Serve: Serve chilled and garnished with fresh lemon slices and blueberries, if desired. Leftovers will keep in the fridge for up to 3 days; just shake well before serving as the blueberries will settle.
