Final answer:
The word 'masterpiece' is used connotatively in the sentence to imply a work of art and exceptional skill in cooking, beyond simply being a well-cooked dish.
Step-by-step explanation:
The word that is used in a primarily connotative way in the given sentence is 'masterpiece'. Connotative language refers to a meaning that is implied by a word apart from the thing which it describes explicitly. 'Masterpiece' conveys more than just a well-cooked dish; it suggests a work of art, crafted with exceptional skill, and is often associated with the peak of someone's creativity or effort in the culinary arts. Words like 'cooked', 'recipe', and 'exited' are more denotative, providing a direct, specific meaning without additional implications.
