We ate at a lovely-looking restaurant in Kerala about 4 years ago - to set the scene, it looked a bit like the beach in the background here:
Beautiful.
I had the fresh fish, it looked and smelled absolutely amazing; firm, moist white fish in a dry paste, barbecued about 20 yards from where it'd been dragged out of the sea.
in my defence, i sweat quite a lot anyway, it was 35 degrees and probably over 90% humidity.
I've never felt worse than about 3 seconds after the first bite of my lunch. The locals absolutely fell about laughing as I went red, then purple, then (apparently) a funny blue colour. I couldnt speak, didnt trust myself to talk and couldnt feel my mouth at all. My sweat glands went into overdrive and within seconds my face was absolutely dripping.
no, I didnt finish it. Even after several lassis and a couple of kingfishers my mouth was still bloody sore several hours after that one bite. Mrs Mike, who had wisely gone for a different menu option, thought it was hilarious.
