Burns topsides cooking in dish (5-4,4)
I believe the answer is:
birds-nest soup
'dish' is the definition.
(I've seen this before)
'burns topsides cooking' is the wordplay.
'cooking' indicates anagramming the letters (letters cooked up into a new form).
'burns'+'topsides'='burnstopsides'
'burnstopsides' with letters rearranged gives 'BIRDS-NEST SOUP'.
'in' is the link.
(Other definitions for birds-nest soup that I've seen before include "Chinese dish" , "Chinese delicacy" .)
