Step 1

Combine the lemon juice, water, maple syrup, and basil leaves in a blender, and blend until the basil is completely broken down. No need to strain! (If your basil leaves are particularly large, start with just 2 leaves, and add more to taste.)

Step 2

Serve over ice right away, or store it in the fridge in an airtight container for up to 3 days.
