I know this drink is in no way representative of the city of Chattanooga (apologies if you live in Tennessee) but I just like the name. It just kinda rolls off the tongue, and the drink turned out quite well too.
1 1/4 oz white whiskey
3/4 oz rose petal liqueur
3/4 oz peach shrub
Pour over plentiful ice in a Collins glass and add 2-3 oz of soda water to taste. Stir well and garnish with a lemon wheel.
I know, I know - you'll have to make two of these ingredients yourself. Neither is too hard, really. For the liqueur, combine 1 tablespoon dried rose petals with 1 cup 100-proof vodka and 1/2 cup of regular simple syrup (a 1:1 ratio of water to sugar) then let infuse for a week or so. The shrub is even more flexible, if a bit more difficult, although you can make as much or as little as desired. Just take 1 part chopped and pitted fresh peach, and add 1 part apple cider vinegar or champagne vinegar. Let this infuse in the refrigerator for a week, then strain and add 1 part sugar. Keep this in the fridge, shaking every day for a week or so until the sugar has all dissolved, then use wherever - non-alcoholic sodas, cocktails such as the one above, or on top of pancakes. Seriously, that last one is worth a shot.
