Cooked meats home help carved on lake (11)
I believe the answer is:
charcuterie
'cooked meats' is the definition.
(term for cold cooked meats)
'home help carved on lake' is the wordplay.
'home help' becomes 'char' (char can mean a cleaner).
'carved' becomes 'cut'.
'on' says to put letters next to each other.
'lake' becomes 'Erie' (Lake Erie is one of the Canadian/US 'Great Lakes').
'char'+'cut'+'erie'='CHARCUTERIE'
(Other definitions for charcuterie that I've seen before include "Deli" , "Cold cooked meats shop" , "Delicatessen" , "butcher's" .)
