Spanish cooking pot found in Holland? (4)
I believe the answer is:
olla
'spanish cooking pot' is the definition.
(I've seen this in another clue)
'in holland?' is the wordplay.
'in' says the answer is hidden in the clue.
'OLLA' can be found hidden inside 'holland'.
'found' is the link.
(Other definitions for olla that I've seen before include "hash" , "Urn" , "16 across [STEW]" , "jar" .)
