COMBINE & BLEND. In a high-speed blender, add lemon, sweetener, and 4 cups water. Blend until smooth, usually 1-2 minutes.
ADJUST. Taste and adjust sweetener and lavender, if needed. Give it another quick blend.
STRAIN. Strain the lemonade through a fine mesh colander.
CHILL. Transfer the lemonade to a bottle or jar and chill. Or enjoy immediately over ice.
ENJOY!
