Substituted gin with vodka this time. Left the ratios the same, lest I get confused by too many changing variables. Partway through putting ice in the glass, it occurred to me that crushed ice might be the answer to the dispersal of the bitters. So I tried adding some crushed ice on top of the normal rocks.
Results: No Improvement
Crushed ice layer did appear to slow down the rate of dispersion, but not enough. I’ll have to try 100% crushed ice (instead of 25%) next time.
I’ve also noticed that not only is the green tea not so truly green, but the bitters aren’t so truly red. So instead of green with red floating on top, I have yellow/green with brownish/red on top. (Well, the brownish red has invaded the entire glass now, but it STARTED on the top!) I may need different ingredients altogether to achieve the desired visual effect.
The green tea shines through more clearly in this incarnation. As do the bitters, for that matter. Perhaps too much so. Guess I was a bit overzealous with the “blood” on the top. Maybe a few dashes would suffice.
When experiment was complete, I realized I should capture it on film (or SD card, as the case may be). It was kinda pretty, actually—the bitters were streaming down into the glass almost like little rivers of brownish blood. So I ran to get my camera, hoping to immortalize it before the bitter dispersion was complete.
By the time I’d retrieved my camera and returned to the laboratory (kitchen?), bitter dispersal was complete. Will need to plan ahead in the future.
Also still need to retrieve proper ice cubes from my boyfriend’s place. Cursing my own poor memory.
