Treat for starters consumed hot or cold (4)

I believe the answer is:
choc
'treat' is the definition.
The definition and answer can be both things that one consumes for nourishment as well as being singular nouns.
Perhaps there's a link between them I don't understand?
'starters consumed hot or cold' is the wordplay.
'starters' suggests taking the first letters.
The first letters of 'consumed hot or cold' is 'CHOC'.
'for' is the link.
Can you help me to learn more?
(Another definition for choc that I've seen is " Sweet (abbr)".)
