My wife and I brew an "off the wall" saison every summer. This past summer we got married and went to Egypt for the honeymoon. While there, we got the amazing idea of making our saison Egyptian inspired (Beat DFH to the punch!). We bought our additions from the Souks (markets) in Aswan and Luxor, Egypt. We brewed it with coriander, lemon grass, ginger, and hibiscus flowers.
The hibiscus flowers gave a pink hue and a light tart cranberry flavor. Turned out great! You can find dried hibiscus flowers at a middle eastern market. Good luck!
