I'm a little stuck... Click here to teach me more about this clue!

'fuel in pinch of tobacco kerosene' is the definition.
'coke' can be an answer for 'kerosene' (thesaurus). I am not sure about the 'fuel in pinch of tobacco' bit.

'of tobacco kerosene' is the wordplay.
'of' indicates a hidden word.
'COKE' is hidden within 'tobacco kerosene'.

Can you help me to learn more?
