“Amplitude” is the word sensory experts use to describe flavors that are well integrated and balanced in a given product. When a dish is said to be high in amplitude, it means that it gives one an overall impression of balance, unity, and harmony, with no one individual flavor note jumping out above the rest. What it really means is that the dish is designed to hit the primal points of the sweet, sour, salty, bitter, and umami, all at once.
Amplitude is not necessarily indicative of high quality or hedonic characteristics (a good example is Coke, or Heinz ketchup, both of which are amazing, high amplitude products (see Malcolm Gladwell’s essay “The Ketchup Conundrum” http://www.gladwell.com/2004/2004_09_06_a_ketchup.html).
It would also seem that high-amplitude, universally liked products tend to fall into one of the two categories: full-flavored & balanced, or subtle & balanced. The American palate certainly favors the former, – intense, rich, heavily extracted, powerful flavors. Think commercially produced American basil pesto versus Italian homemade pesto…
I will take this further and say that the combination of balance and subtlety (which is so hard to come by in the US) signals a serious commitment to quality. One such place (visited on our most recent NYC trip) is Sakagura, one of the top izakaya in this country housed in the basement of a Midtown office building. An izakaya is a drinking establishment serving good food (essentially a Japanese wine bar); therefore, the menu at Sakagura is supposed to play a mere supporting role to the 200+ sakes on its list. To me, these simple, pure, understated dishes do more than that…
