UPDATE March 19 2012: Camper has dubbed this the Pom-Pom. So it shall be.
0.5 oz cinnamon-vanilla-pomelo syrup
0.5 oz UB Dessert Vinegar Pomegrante Comdiment**
1 oz water
2.5 oz ginger soda
Sake first three ingredients over ice in a shaker. Pour over crushed ice into a rocks glass. Top with ginger soda. Garnish with a candied pomelo slice.
The other night I tried to make a shrub or some sort of drinking vinegar. All attempts came out poorly. Last night I decided to slice up some pomelo and simer it in my cinnamon-vanilla syrup. The result was something that may or may not resemble Don's Mix. Though it likely resembles Don's Mix moreso than it resembles, say, a spare tire, it probably is only vaguely similar. Anyway, tonight I was looking for some refreshment and didn't want to (yet again) reach for a bottle of fizz, corn syrup and food colouring. Instead I combined vinegar, white sugar and fizz, corn syrup and food colouring.
Baby steps, man, baby steps.
