Beams, seeing pudding following starter of risotto (7)
I believe the answer is:
rafters
'beams' is the definition.
(rafter is a kind of beam)
'pudding following starter of risotto' is the wordplay.
'pudding' becomes 'afters' (I've seen this before).
'following' means one lot of letters go next to another.
'starter of' suggests taking the first letters.
The initial letter of 'risotto' is 'r'.
'afters' after 'r' is 'RAFTERS'.
'seeing' is the link.
(Other definitions for rafters that I've seen before include "Internal roof beams" , "Roof supports" .)
