الأخشاب التي يتم استعمالها كفحم للشواء هي أخشاب النارنج والتوت اليابس

It's talking about the wood needed for cooking masgouf [barbequed fish] in Iraq. Full article is here:

I know توت is mulberry, but the word also seems to have a more generic meaning of "berry". So this might mean "dry berry", or "dry mulberry" or some other berry.

Thank you for any help!
