Part of fridge is more bracing (7)
I believe the answer is:
crisper
'more bracing' is the definition.
Both the definition and answer are comparative adjectives. Maybe they are linked in a way I don't understand?
'part of fridge is' is the wordplay.
I cannot really see how this works, but
'is' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for crisper that I've seen before include "Crunchier, or more cold and bright" , "Fridge fruit and vegetable compartment" .)
