Something sentimental to follow snack (4,3)
I believe the answer is:
corn dog
'something sentimental' is the definition.
I know nothing about this answer so I cannot tell whether this works.
'follow snack' is the wordplay.
I cannot quite understand how this works, but
'follow' could be 'dog' (dog can mean to follow or torment) and 'dog' is found within the answer.
The remaining letters 'corn' is a valid word which might be clued in a way I don't see.
This explanation may well be incorrect...
'to' is the link.
Can you help me to learn more?
(Another definition for corn dog that I've seen is " A battered sausage on a stick".)
