Melted chocolate drunk without stopping (6-3-5)

I believe the answer is:

around-the-clock

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

'melted chocolate drunk without stopping' is the definition.
I can't judge whether this defines the answer.

'melted chocolate drunk' is the wordplay.
'melted' is an anagram indicator.
'chocolate'+'drunk'='chocolatedrunk'
'chocolatedrunk' anagrammed gives 'AROUND-THE-CLOCK'.

Can you help me to learn more?

(Another definition for around-the-clock that I've seen is " All day".)

I've seen this clue in The Telegraph.
