Produced in Madeira (4)
I believe the answer is:
made
'produced' is the definition.
('make' can be a synonym of 'produce')
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for made that I've seen before include "Manufactured" , "Produced" , "Performed" , "Forced" , "One renovating (painting)" .)
