Was it his mouth or his kitchen? I remember a post about someone who ordered a sweetener from some Chinese industrial supplier and accidentally spilled/destroyed the packaging in his kitchen, making everything cooked there taste sweet for a long time.

It sounded like sucralose(although it turned out to be neotame).

Sucralose is very potent, one knife tip sweetens 4l of water and the powder is very fine and tends to linger around. It's also very cheap.

Possibly - The one I recall just had a hobby of trying out experimental sweeteners.
