Let's 1st add a fun rim to this yummy cocktail. I like to add sugar mixed with some dried rose petals. You can omit the roses if you aren't into that kind of thing. Start off by adding your ingredients to a cocktail shaker. The rose green tea, guava nectar, rose water, simple syrup, and ice. Shake it up! Shake it real good! Pour into a glass. It’s going to be sweet, so adding sparkling water will less the sweetness and add fun bubbles to the mix. If you like more, do more! Then garnish with some more rose petals and a dried citrus to really give that mocktail some love. Cheers!
