Desserts put in nice sauces (4)
I believe the answer is:
ices
'desserts' is the definition.
(ice is a kind of dessert)
'in nice sauces' is the wordplay.
'in' indicates the answer is hidden within the clue.
'ICES' is hidden in the letters of 'nice sauces'.
'put' acts as a link.
(Other definitions for ices that I've seen before include "Decorates cake with sugar topping" , "Kills (slang) - sweets" , "Cones etc" , "Decorates cakes with frosting" , "summer refreshment" .)
