French way of cooking easily with no nuts acquires name (9)
I believe the answer is:
lyonnaise
'french way of cooking' is the definition.
I can't judge whether this defines the answer.
'easily with no nuts acquires name' is the wordplay.
'with' says to put letters next to each other.
'nuts' indicates an anagram (nuts can mean crazy).
'acquires' indicates putting letters inside.
'name' becomes 'n' (common abbreviation e.g. on forms).
'easily'+'no'='easilyno'
'easilyno' is an anagram of 'lyonaise'.
'lyonaise' enclosing 'n' is 'LYONNAISE'.
Can you help me to learn more?
(Other definitions for lyonnaise that I've seen before include "cooked in a way to make you cry?" , "Served with onions" , "cooking with onions" , "(Of potatoes) cooked with onions in a wine sauce" .)
