Flavour for the sake of "manners"

Before today I never chewed with my mouth open, it went against my natural chewing technique, but today for whatever reason I left my mouth slightly open whilst eating and when I realised I closed it, and I noticed something and on further experimentation I realised that the food actually tasted slightly better when my mouth was open. Maybe it's only with certain foods but sometimes the airflow enhances the flavour! Please try it yourself and tell me if you notice and differences so you can confirm if I'm crazy or not.

Well, it's all about senses. Dull one and the other ones are naturally hightened. So, close your eyes and your sense of taste naturally improves. The eating with an open mouth thing sounds weird, though. oO

On further experimentation it seems only to apply to warm/hot food

I would sacrifice the flavor for politeness. Also, it's more natural for me to chew with my mouth closed. I would have to make a conscious effort to chew with it open.

I grew up sitting across a table from my grandfather, who always chews with his mouth open.

I think it is the most disgusting thing.

(Unless you're eating like taffy, or chewy caramel or some trout. Then you don't have a choice.)

Yea. Try pinching your nose while chewing. You'll lose most of the taste. Then stop pinching and enjoy the explosion of flavour.

I hate when people eat with their mouth open. smurf that. I am about ready to punch anyone who does it around me.
