In Scotland, it's noted for stone (5)

I believe the answer is:
scone
This could be a double definition.
'in scotland' is the first definition.
Although both the answer and definition are singular nouns, I don't see how they can define each other.
'noted for stone' is the second definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
'it's' acts as a link.
Can you help me to learn more?
(Other definitions for scone that I've seen before include "Unsweetened cake" , "Plain teatime cake" , "tea time treat" , "A little cake" , "baked cake" .)
