More bracing part of the fridge (7)
I believe the answer is:
crisper
'more bracing part of the fridge' is the definition.
I can't judge whether this defines the answer.
'bracing part of the fridge' is the wordplay.
'bracing' becomes 'crisp' (I've seen this before).
'part of the fridge' becomes 'er' (I can't explain this - if you can you should believe this answer much more).
'crisp'+'er'='CRISPER'
Can you help me to learn more?
(Other definitions for crisper that I've seen before include "Fridge fruit and vegetable compartment" , "Crunchier, or more cold and bright" .)
