Italian sauce made from ripest olives? (5)
I believe the answer is:
pesto
'italian sauce' is the definition.
(I've seen this in another clue)
'from ripest olives?' is the wordplay.
'from' says the answer is hidden in the clue.
'PESTO' can be found hidden inside 'ripest olives'.
'made' acts as a link.
(Other definitions for pesto that I've seen before include "sauce involving Basil" , "Pasta sauce mainly of basil and cheese" , "Sauce of basil, pine nuts, etc" , "Basic sauce" , "Basil-based sauce" .)
