Add the dried hibiscus flowers to the bottle of tequila. Put the lid on and let it sit for 2 to 3 weeks.
When you are ready to mix your cocktail, pour all the ingredients into a shaker.
Shake well and pour into two glasses full of ice.
If you use honey to sweeten this cocktail it can sometimes take some extra stirring or shaking to combine. OR you can heat up the water slightly first and mix the water and honey together before adding to the cocktail mixture.
