Recollects one Islamic leader consuming duck with a kind of island cheese (8)
I believe the answer is:
halloumi
'cheese' is the definition.
(I've seen this before)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for halloumi that I've seen before include "Traditional Cypriot cheese" , "Cheese from Cyprus" , "Greek dish of fried goat's cheese" , "Cypriot goat's or sheep's milk cheese" .)
