I’ve never heard someone refer to a European dish as having umami, it’s just upper class people showing how cultured they are by knowing the Japanese word for savory flavor. To top it off it only gets used when talking about the big three Asian countries. No one is talking about the umami profile of Vietnamese food. It’s the same kind of Anglo person who would read Sun Tzu while drinking lapsang souchong in the mid 20th century. Both are fine things, but together you know this guy is sad about the fall of the British Empire.
It's just the name for the flavor, it's more racist to refuse to use the word because it's a Japanese loan word imo? A lot of commonly-euro ingredients also add an umami base to their respective dishes, like worcesteshire sauce, anchovy paste, mushrooms, and tomatoes. Many dishes do need an umami component to taste good, especially places with a weak culinary tradition (br*tain). Just because white food bloggers are cringe doesn't mean using a Japanese loan word is racist
bacon is umami too and tbh that's 90% of what I hear umami referencing personally, then again I don't really look on the food side of the internet too much.
