Solve this tricky crossword clue: The best part of an apple?

As a detective trying to solve the mystery of the crossword clue, I approached it with a systematic thought process. I first analyzed the clue itself and saw that it contained an exclamation indicating some level of disagreement or confusion. Upon reading further, it became apparent that a part of an apple was being discussed that was contrary to the common belief of it being a less desirable part. Based on this insight, I began to think of synonyms for beliefs or convictions that one may hold about apples. As I considered this, I remembered the term “core belief“, which refers to a fundamental belief about oneself, others, and the world that influences one’s behavior and attitudes. The word ‘core’ also tied in with the apple’s core, the part in question. Finally, I put the two words together, and the answer ‘COREBELIEF‘ appeared before me. I was able to solve the mystery of the crossword clue through breaking it down, analyzing the language used, and considering various possibilities, ultimately gaining the insight necessary to arrive at the correct answer.
