What is the correct adjective to describe when something is fried for too long or at a high heat? To fry "strong"? To fry "hard"? Can't pick the word that would sound authentic.
Are participles allowed? If so, an adverb plus the participle are idiomatic: for example, over fried or badly fried or excessively fried. In many contexts, charred, over cooked, or burnt would also work.
