flash in the pan

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

'an instant hit' is the definition.
'flash in the pan' can be an answer for 'hit' (thesaurus). I am unsure of the 'an instant' bit.

'light and fashionable the cooking vessel' is the wordplay.
'light' becomes 'flash' (flash is a kind of light).
'and' is a charade indicator (letters next to each other).
'fashionable' becomes 'in' (similar in meaning).
'cooking vessel' becomes 'pan' (I've seen this before).
'flash'+'in'+'the'+'pan'='FLASH IN THE PAN'

'is' is the link.

Can you help me to learn more?
