What is needed to make its dough (3)
I believe the answer is:
tin
'dough' is the definition.
(thesaurus)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for tin that I've seen before include "Element, symbol Sn" , "roofing material" , "Silvery white metal" , "Silvery-white metal used in cans" , "Ready" .)
