I don't know what you want. You've asked the same question at least
four times and gotten the same answer about four times. The bitterness
is the result of the interaction between the object and the sense of
taste. From the fact that X tastes bitter to Y, we learn something
about X and something about Y. We can sometimes separate them,
sometimes not.
