National register for cake? (5,4)
I believe the answer is:
swiss roll
'cake?' is the definition.
(I've seen this before)
'national register' is the wordplay.
'national' becomes 'swiss' (I can't justify this - if you can you should believe this answer much more).
'register' becomes 'roll' (list of names).
'swiss'+'roll'='SWISS-ROLL'
'for' is the link.
Can you help me to learn more?
(Other definitions for swiss roll that I've seen before include "piece of cake?" , "Somehow sponge" , "teatime treat?" , "Filled sponge cake" , "Type of sponge cake" .)
