Special cocktail with a drop of lemon and myrtle pepper (8)
I believe the answer is:
allspice
'myrtle pepper' is the definition.
'allspice' can be an answer for 'pepper' (I've seen this before). I am not certain of the 'myrtle' bit.
'special cocktail with a drop of lemon' is the wordplay.
'cocktail with' is an anagram indicator.
'a drop of' suggests taking the first letters.
The initial letter of 'lemon' is 'l'.
'special' anagrammed with 'l' makes 'ALLSPICE'.
'and' acts as a link.
Can you help me to learn more?
(Other definitions for allspice that I've seen before include "fragrant plant" , "Aromatic dried fruit of a Caribbean tree" , "Pimento or Jamaica pepper" , "Pill case (anag.)" , "Aromatic West Indian tree" .)
