Some sauce destroyed the puck (7)
I believe the answer is:
ketchup
'some sauce' is the definition.
(ketchup is a type of sauce)
'destroyed the puck' is the wordplay.
'destroyed' indicates an anagram.
'the'+'puck'='thepuck'
'thepuck' anagrammed gives 'KETCHUP'.
(Other definitions for ketchup that I've seen before include "Sauce made largely of tomatoes" , "Relish" , "Piquant sauce, often tomato based" , "Spicy tomato sauce" , "Condiment" .)
