Cook small quantity of baked beans, perhaps, for islander (9)
I believe the answer is:
dominican
'for islander' is the definition.
(I've seen this before)
'cook small quantity of baked beans' is the wordplay.
'cook' becomes 'do' (do can mean to cook).
'small' becomes 'mini' (short for miniature).
'quantity of baked beans' becomes 'can' (I can't explain this - if you can you should give a lot more credence to this answer).
'do'+'mini'+'can'='DOMINICAN'
'perhaps' is the link.
Can you help me to learn more?
(Other definitions for dominican that I've seen before include "Member of an order of friars" , "Religious" , "sister of Caribbean descent" , "Republican" , "person in the WI" .)
