Take kung pao chicken as an example.
We can separate some flavors, sour, sweet, spicy and salty.
When these flavors are mixed together, what kind of flavor is it?
We don't spend more effort to create words or words that can directly describe it.
If we opportunistically say that this dish is salty, spicy, sour and sweet, it is equal to not saying it; If we are glib and call it delicious, it is still equal to saying nothing, because explaining "delicious" is an impossible task and more "concepts" about taste should be introduced.
If we gave up, we decided to use "delicious" to describe it, but that was only a description of our taste buds, not the characteristics of the dish itself.
Of course, when we say "sweet, sour, spicy and salty", we also rely on feelings, but these feelings and concepts are in one-to-one correspondence, which is why there is such an allusion as "looking at plum to quench thirst"
"Delicious" and "delicious" are a little lonely.
