Element of fizz in Coke (4)

I believe the answer is:

zinc

'element' is the definition.
(zinc is a kind of element)

'of fizz in coke' is the wordplay.
'of' says the answer is hidden in the clue.
'ZINC' is hidden in the letters of 'fizz in coke'.

(Other definitions for zinc that I've seen before include "Silvery-white metal" , "Metal used in galvanising iron" , "Type of metal" , "Blue-white metallic element, atomic number 30" , "Blusish-white lustrous metallic element" .)

I've seen this clue in The Telegraph.
