Accountant tucking into reddish-purple almondy biscuit (8)
I believe the answer is:
macaroon
'biscuit' is the definition.
(I know that macaroon is a type of biscuit)
'accountant tucking into reddish-purple' is the wordplay.
'accountant' becomes 'CA' (abbreviation for chartered accountant).
'tucking into' means one lot of letters goes inside another.
'reddish purple' becomes 'maroon' (maroon is a purplish colour. I am not sure about the 'reddish' bit.).
'ca' inserted within 'maroon' is 'MACAROON'.
'almondy' is the link.
I am not very happy about this link. It may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for macaroon that I've seen before include "Light biscuit" , "cake" , "Chewy biscuit containing almond paste" , "Biscuit made with almond paste" , "Coconut-topped biscuit" .)
