Pinches cold food that might be spare? (5)

'pinches' is the definition.
The answer and definition can be both to do with contact as well as being verbs in their -s form.
Maybe there's an association between them I don't understand?

'cold food that might be spare?' is the wordplay.
I cannot quite understand how this works, but
'cold' could be 'c' (eg on taps) and 'c' is found within the answer.
'food' could be 'rib' (rib is a kind of food) and 'rib' is found in the answer.
A single letter 's' remains which might be clued in a way I don't see.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
