In a cocktail glass, combine the orange juice, orange bitters, and chili oil. Stir gently to blend the flavors.
Add ice to the top of your glass. Pour in Fiore Frizzante, stirring gently to combine without losing the fizz.
Garnish with an orange slice or an orange rose for a bold presentation. Sip and enjoy the refreshing citrus with a subtle heat that lingers on the finish!
