Caterer cooked with coal and gas? (11)
I believe the answer is:
accelerator
'and gas?' is the definition.
I can't judge whether this defines the answer.
'caterer cooked with coal' is the wordplay.
'cooked with' indicates anagramming the letters (letters cooked into a new form).
'caterer' anagrammed with 'coal' can make 'ACCELERATOR'.
Can you help me to learn more?
(Other definitions for accelerator that I've seen before include "Right-hand car pedal" , "A car foot pedal" , "Substance speeding up a chemical process" , "It increases road speed" , "Throttle" .)
