Recipe request

Does anyone have a good recipe for teriyaki sauce ? I'm after the thick, sticky kind which is served in some Japanese restaurants. Not the thin kind (although that's good as a marinade), which is also served in some Japanese restaurants :)

Failing that, can anyone recommend a brand of buyable sticky sauce ?

Sniff, sniff, sneeze, sneeze, SNEEZE, sniff

Oh. It's not an allergic reaction, then. It's a cold. Bugger. I don't remember ordering one of those.
