Start out by boiling the water. Once hot fill a pitcher with 6 cups of water and add 3 tsp of the loose hibiscus tea in 2 stainless steel tea ball infusers. Alternatively, you can use tea bags, but you will have to use 6.
Add the lavender extract and let it steep for 2O minutes. Taste and decide if you want to add the honey or not. You can also add more honey if you prefer it sweeter The hibiscus flavor will be very subtle at this point so don't worry about that.
Let it come to room temperature for about 2 hours before transferring it into the fridge overnight (or for a minimum of another 2 hours). The tea ball infusers or teabags will stay in there the whole time. This intensifies the flavor, the longer it infuses the stronger the hibiscus taste. If you need to speed up the process you could also add more tea in the beginning.
Once it is ready to serve add ice cubes to your liking. Just keep in mind that depending on how many you will use it will dilute the flavor.
