Could mite love basil paste? (5)
I believe the answer is:
pesto
'basil paste?' is the definition.
I know nothing about this answer so I cannot judge whether this works.
'could mite love' is the wordplay.
'could mite' becomes 'pest' (I am not sure about this - if you are sure you should believe this answer much more).
'love' becomes 'o' (love means zero in tennis).
'pest'+'o'='PESTO'
Can you help me to learn more?
(Other definitions for pesto that I've seen before include "Pasta sauce based on basil" , "Pasta sauce mainly of basil and cheese" , "Basil-based sauce" , "Green sauce" , "A sauce served with pasta" .)
