Drink, some hot I gathered (8)
I believe the answer is:
smoothie
'drink' is the definition.
(smoothie is a type of drink)
'some hot i gathered' is the wordplay.
'gathered' is an anagram indicator (the letters are gathered into a new order).
'some'+'hot'+'i'='somehoti'
'somehoti' is an anagram of 'SMOOTHIE'.
(Other definitions for smoothie that I've seen before include "Glib speaker" , "Fruit pured with milk" , "Thick, drink of pureed fruit" , "Drink made with pureed fruit" , "Dairy fruit drink" .)
