I was at the Distraction Club last night, and I had a shot of this, as supplied by Ivan 'mad drummer' Sheppard.
It's a vodka infused with the Ghost Pepper (aka Naga Jolokia) Chilli.
It does produce quite a nice glow, but having it with no run up gave me my instant hiccoughs.
Yes, I have two odd reactions to chilli heat.
The first — as above — happens when I take a good dose all at once, with no lead in. In those cases, I often get instant hiccoughs, after only a handful of seconds. It doesn't last very long, but I do feel a bit silly.
My other reaction is that my scalp sweats.
That second one can happen even when I don't actually have much heat impact. Sometimes it's the only way I know is something is really hot, because the thing about chilli heat is it's something you acclimatise to, and that acclimatisation is something that can occur during the meal itself. If I'm idling over a meal, and the first few bites are relatively mild, I don't get the impact, but my body realises that heat is coming up, and it recalibrates ready. So I can end up eating quite hot curry, and yet the only symptom is my scalp getting moist.
In the case of the vodka, my scalp stayed dry, even though my mouth spent a couple of minutes going "Hey, hey, that wasn't fair" before settling down to a warm (and not unwelcome) glow.
