Limonana (Middle Eastern Frozen Mint Lemonade)

Add the sugar and 5 tablespoons of water to a small saucepan; heat over medium heat, stirring constantly, until the sugar is dissolved. Cool to room temperature.

Add the cooled sugar syrup, remaining cup water, lemon juice, mint leaves, ice cubes, and orange blossom water (if using) to a blender. Pulse a few times to break up the ice and then process until slushy.

Pour into 2 tall glasses, garnish with mint leaves if desired, and serve immediately.
