I'm VERY interested in this one. Keep us informed. I loved the ginger idea and used the Lemongrass Ginger Ale recipe from AHS. Everybody here found it interesting and thought we should experiment more with it, but the recipe just needed something different done, particularly with the Ginger as you could taste it fine, but it really did just hit the back of your throat with the taste. We were thinking of adding it with 5 minutes to go instead of 10 so it approached the aroma instead of the flavor. Your approach is really pushing it, but I could see the ginger reacting favorably as well. Boiling it produced very different reactions than I would have expected. Powering it in like your recipe could be wonderful if there is a touch more sweetness to mellow the ginger somewhat. Honey is a good way to do it I would think.
