Superheroes never cooking with gas (8)
I believe the answer is:
avengers
'superheroes' is the definition.
I can't tell whether this defines the answer.
'never cooking with gas' is the wordplay.
'cooking with' is an anagram indicator (letters cooked up into a new form).
'never' anagrammed with 'gas' gives 'AVENGERS'.
Can you help me to learn more?
(Other definitions for avengers that I've seen before include "1960s TV series with Steed and Emma Peel" , "They retaliate" , "They seek or inflict retribution" , "Agents of retribution" , "Retaliating fighters" .)
