for simple syrup---
1 cup sugar
1 cup water
2 large blood oranges
2 cups sparkling Italian mineral water
2 tbsp prepared simple syrup (or to taste)
To make simple syrup, combine sugar and water in a saucepot on the stove and bring to a simmer. Continue to simmer while stirring until all sugar has been dissolved. Take pan off heat and let cool before storing simple syrup in the fridge (I store mine in a mason jar and it lasts me about two weeks or so).
To make sodas, juice oranges and then strain juice into a large glass. Add soda water and prepared simple syrup to taste. Serve.
5 minutes (not including time to prepare and chills simple syrup)
