Prepare the glasses: Rub a little lemon around the rim and dip it in dried rose petals or sugar if you want a decorative rim.

Add 1 tbsp rose syrup to each glass.
Add ½ tbsp lemon juice to each glass and gently mix. Add plenty of ice cubes.

Give it one gentle stir—don't overmix, so you keep the pretty rose-and-coconut layers. Garnish with fresh rose petals + a lemon slice. I used some mint leaves for garnishing.
