A complex claret - round, initially aromatic and from a nice menu presumably
I believe the answer is:
a la carte
'from a nice menu presumably' is the definition.
I can't tell whether this defines the answer.
'a complex claret round initially aromatic' is the wordplay.
'complex' indicates anagramming the letters.
'round' means one lot of letters goes inside another.
'initially' suggests taking the first letters.
The initial letter of 'aromatic' is 'a'.
'claret' with letters rearranged gives 'lcarte'.
'lcarte' enclosing 'a' is 'lacarte'.
'a'+'lacarte'='A LA CARTE'
'and' acts as a link.
Can you help me to learn more?
(Other definitions for a la carte that I've seen before include "Type of menu" , "It suggests lots of possibilities" , "Menu with individually-priced dishes" , "The more expensive menu" , "Menu with items indiviually listed and priced" .)
