Hibiscus flower soda

1. Boil the cup of water with the hibiscus flowers and panela for 5 minutes: you will get an intense red concentrate.
2. Strain and let cool completely.
3. Divide the concentrate into two glasses with ice.
4. Top with cold sparkling water, a touch of lime, and stir gently to keep the fizz.

Tip: whole hibiscus flowers give a color and acidity no powder can match.
