Find meal out red-hot (8)
I believe the answer is:
inflamed
'red-hot' is the definition.
(thesaurus)
'find meal out' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'find'+'meal'='findmeal'
'findmeal' anagrammed gives 'INFLAMED'.
(Other definitions for inflamed that I've seen before include "Swollen, hot, red" , "Red and sore" , "Provoked (someone) to strong feelings" , "one so hot and bothered" , "Aggravated; red" .)
