One turning over dough is very rich and secure (7,3)
I believe the answer is:
rolling pin
'one turning over dough is' is the definition.
Although both the answer and definition are singular nouns, I can't understand how one could define the other.
'rich and secure' is the wordplay.
'rich' becomes 'rolling' (rolling in it).
'and' says to put letters next to each other.
'secure' becomes 'pin' (pinning is a kind of securing).
'rolling'+'pin'='ROLLING-PIN'
'very' acts as a link.
Can you help me to learn more?
(Other definitions for rolling pin that I've seen before include "Baker's tool" , "Kitchen implement" , "It helps make pastry" , "Baking aid" , "kitchen item found" .)
