The Fifth Flavor
While the standard flavors of salty, sweet, sour, and bitter are obvious to us and easy to experience, the fifth flavor— umami—is ineffable. It’s the salience of parmesan cheese, anchovies, dried tomatoes, fish sauce, and dashi. Though it can be oversaturated and overused, umami is an essential taste modifier that makes the sum of its parts stronger when it’s properly used.
Animation plays a role similar to umami to elevate good design to a more satisfying experience.Animation handbook
