What's best with tart? (4,5)
I believe the answer is:
sour cream
'what's best with tart?' is the definition.
I can't judge whether this definition defines the answer.
'best with tart?' is the wordplay.
'best' becomes 'cream' (both can mean the elite).
'with' is a charade indicator (letters next to each other).
'tart?' becomes 'sour' ('sour' can be similar in meaning to 'tart').
'cream' put after 'sour' is 'SOUR CREAM'.
Can you help me to learn more?
(Other definitions for sour cream that I've seen before include "Fermented dairy product" , "cooking ingredient" , "salad dressing" , "Rich savoury food" , "dip" .)
