Patrol Lake Como for some cooking pot? (4)
I believe the answer is:
'pot?' is the definition.
'patrol lake como for some cooking' is the wordplay.
'OLLA' is hidden within the letters.
But, I'm not sure how this is indicated.
Can you help me to learn more?
(Other definitions for olla that I've seen before include "hash", "16 across [STEW]", "Urn", "jar".)
