Hot sweet endlessly served up for associate (6)

I believe the answer is:

hobnob

'for associate' is the definition.
(to hobnob with people is to associate with them)

I don't understand the rest of the clue.

(Other definitions for hobnob that I've seen before include "Mix socially with the biscuit" , "Associate familiarly" , "Associate informally" , "Spend time chatting to a VIP?" , "Socialise informally" .)

I've seen this clue in The Times.
