Let's cook.
In a small saucepan, combine the water and honey. Bring to a gentle simmer over medium heat, stirring until the honey is fully dissolved. Remove from heat.
Stir in the orange blossom water into the honey syrup. Let the syrup cool completely to room temperature.
Divide half of the Greek yogurt among four serving glasses or small bowls.
Drizzle a portion of the cooled orange blossom honey syrup over the yogurt in each glass.
Sprinkle a spoonful of chopped pistachios over the syrup layer.
Add the remaining Greek yogurt to each glass, creating a second layer.
Drizzle with the remaining orange blossom honey syrup and top with the rest of the chopped pistachios.
Serve immediately or chill for at least 30 minutes for a colder dessert.
