Error: interestingly | Correction: interesting
(The sentence requires an -ing adjective to describe the noun "dish", not an adverb.)
The word "enough" follows an adjective, not an adverb — e.g., "interesting enough." The -ing adjective describes a quality of the dish (it causes interest), so "interestingly" (adverb) is incorrect. Refer to the -ing/-ed adjective rule from the textbook exercise.
