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

'joint' is the definition.
(synonyms)

'central to cairo a strip' is the wordplay.
'ROAST' is hidden within the letters.
But, I am unsure how this is indicated.

Can you help me to learn more?

(Other definitions for roast that I've seen before include "Pull to pieces" , "open-air party in US" , "Reprimand - cook" , "Cooked like chestnuts tonight" , "traditional meal" .)

I've seen this clue in The Independent.
