Instant tea and dark brown coffee (5)
I believe the answer is:
mocha
'dark brown coffee' is the definition.
'mocha' can be an answer for 'coffee' (mocha is a kind of coffee). I am unsure of the 'dark brown' bit.
'instant tea' is the wordplay.
'instant' becomes 'mo'.
'tea' becomes 'cha' (cha is a type of tea).
'mo'+'cha'='MOCHA'
'and' acts as a link.
Can you help me to learn more?
(Other definitions for mocha that I've seen before include "Leather" , "Kind of coffee" , "Coffee drink" , "It may end up as grounds" , "Deep brown; a fine coffee" .)
