... and another has joint I hinder rolling, tucking into cocktail (4,7)

'and another' is the definition.
I know nothing about this answer so I can't judge whether it can be defined by this definition.

'joint i hinder rolling tucking into cocktail' is the wordplay.
I cannot really see how this works, but
'joint' could be 'j' (drug term) and 'j' is present in the answer.
'i' is found in the answer.
an anagram of 'hinder' is 'ihendr' which is located in the answer.
The remaining letters 'mix' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).

'has' is the link.
