Jelly maker to go round with others? (7)

'jelly maker' is the definition.
(heel of a cow made into jelly)

'go round with others?' is the wordplay.
'go round' becomes 'wheel' (I've seen this before).
'with' means one lot of letters go next to another.
'others?' becomes 'co' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'wheel' put after 'co' is 'COWHEEL'.

'to' is the link.
