I was watching this interview on TV, I've heard listening helps a lot when you're learning a new language, and this guy said "A sprinkle of sass early in the morning never hurt anyone.", and it was pretty apparent he was being sarcastic.

I'm just curious, is it a correct grammatical construction? Can we use sprinkle (noun) that way? Does, here, sprinkle mean- a little?
