Tea with a touch of nutmeg added in is extremely fresh (5,3)
I believe the answer is:
brand new
'extremely fresh' is the definition.
'brand new' can be an answer for 'fresh' (I've seen this before). I am not sure about the 'extremely' bit.
'tea with a touch of nutmeg added in' is the wordplay.
'tea' becomes 'brew' (brew can informally mean a cup of tea).
'with' becomes 'and'.
'a touch of' says to take the initial letters.
'added' means one lot of letters go next to another.
'in' is an insertion indicator.
The first letter of 'nutmeg' is 'n'.
'and'+'n'='andn'
'brew' placed around 'andn' is 'BRAND-NEW'.
'is' is the link.
Can you help me to learn more?
(Other definitions for brand new that I've seen before include "without prior experience" , "Mint" , "Latest" , "original" , "Completely fresh" .)
