Odd bits dropping off kitchen freezer? (3)
I believe the answer is:
ice
'freezer?' is the definition.
(something which 'freezes')
'odd bits dropping off kitchen' is the wordplay.
'odd bits dropping off' indicates alternate letters (odd-numbered letters are removed).
The alternate letters of 'kitchen' are 'ICE'.
(Other definitions for ice that I've seen before include "Diamonds, colloquially" , "dessert" , "Finish decorating the Christmas cake" , "Cool down" , "Glaze" .)
