Hot drink extremely tasty with rare ingredient (5)
I believe the answer is:
toddy
'hot drink' is the definition.
(I've seen this before)
'extremely tasty with rare ingredient' is the wordplay.
'extremely' suggests removing the centre (only the extremes of the word are used).
'with' is an insertion indicator.
'rare ingredient' becomes 'odd' (I am not sure about this - if you are sure you should believe this answer much more).
'tasty' with its middle removed is 'ty'.
'ty' going around 'odd' is 'TODDY'.
Can you help me to learn more?
(Other definitions for toddy that I've seen before include "Hot liquor" , "Hot spirituous drink" , "Mixture of spirits, sugar and hot water" , "Hot drink of alcohol" , "Hot drink of spirits with sugar and spices" .)
