Offering at mealtime could make a curate stare (7,5)
I believe the answer is:
tartare sauce
'offering at mealtime could' is the definition.
I can't tell whether this definition defines the answer.
'make a curate stare' is the wordplay.
'make' is an anagram indicator.
'a'+'curate'+'stare'='acuratestare'
'acuratestare' anagrammed gives 'TARTARE SAUCE'.
Can you help me to learn more?
(Other definitions for tartare sauce that I've seen before include "Accompaniment to fish" , "dish accompaniment?" , "Dressing for fish" .)
