Rather cold starter of roast ham (6)
I believe the answer is:
remote
'rather cold' is the definition.
'remote' can be an answer for 'cold' (I've seen this before). I am unsure of the 'rather' bit.
'starter of roast ham' is the wordplay.
'starter of' indicates taking the first letters.
'ham' becomes 'emote' (I've seen this before).
The first letter of 'roast' is 'r'.
'r'+'emote'='REMOTE'
Can you help me to learn more?
(Other definitions for remote that I've seen before include "'Distant, out-of-the-way (6)'" , "Device for controlling apparatus from a distance" , "Far away as meteor (6)" , "TV control device" , "Hand-held TV control" .)
