Wasabi!
You’re probably familiar with the green paste served alongside sushi called wasabi. If you’re unfamiliar, this stuff can burn like hell when you eat too much. So, if you put too much on your sushi and experience the burn, stop breathing through your mouth and rapidly breathe through your nose. This will provide almost immediate relief.
mixing a little of the wasabi in to the soy sauce makes for a great dipping sauce that won't blow out your nostrils.
