As a hot drink it takes some beating (3,3)
I believe the answer is:
egg nog
'some beating' is the definition.
I don't know anything about this answer so I can't judge whether this works.
'as a hot drink' is the wordplay.
I cannot really understand how this works, but
'as' could be 'eg' (I've seen this in other clues) and 'eg' is located in the answer.
'drink' could be 'nog' (nog is a kind of drink) and 'nog' is found in the answer.
A single letter 'g' remains which might be clued in a way I don't see.
This may be the basis of clue (or it may be nonsense).
'it takes' is the link.
Can you help me to learn more?
(Another definition for egg nog that I've seen is " alcoholic drink".)
