I think it's rotted haddock.

I was suffering through this stuff just yesterday due to a counselor's spelling of counsellor. I done figured out that in Commonwealth English, words that end in -l preceded by a vowel usually double the -l when a suffix is added, while in American English the letter is not doubled.   However, for words where two –ll's are preceded by a vowel, the American spelling will retain the doubled consonants when a suffix is added, but, in Commonwealth English, the second –l is dropped when a suffix is added, as in enrollment/ enrolment, skillful/ skilful. I agree with weelittledrummer that it is hard to give a shit. But then I again, I am just noticing that placement of punctuation marks (esp commas) relative to quotation marks and parentheses is transpondally divergent as well, which is going to torment me.
