Sweet stuff husband's culled from Chinese text (5)
I believe the answer is:
icing
'sweet stuff' is the definition.
(I've seen this in another clue)
'husband's culled from chinese text' is the wordplay.
'husband' becomes 'h'.
'culled from' indicates named letters should be taken away.
'chinese text' becomes 'I Ching' (ancient Chinese text).
'iching' with 'h' removed is 'ICING'.
(Other definitions for icing that I've seen before include "Topping in a bag" , "Concreted sugar" , "Showing effect of cold snap" , "Formation of frost on aircraft" , "You could see this on a cake" .)
