Converted Siam dough in Indian Ocean port (9)

I believe the answer is:

mogadishu

I'm a little stuck... Click here to teach me more about this clue!

'indian ocean port' is the definition.
I know nothing about this answer so I cannot judge whether it can be defined by this definition.

'converted siam dough' is the wordplay.
'converted' indicates an anagram.
'siam'+'dough'='siamdough'
'siamdough' anagrammed gives 'MOGADISHU'.

'in' is the link.

Can you help me to learn more?

(Other definitions for mogadishu that I've seen before include "Somali city" , "Capital of Somalia" , "foreign capital" .)

I've seen this clue in The Everyman puzzle in The Observer.
