Biscuit for one turned over in the midst of turning out (6,3)
I believe the answer is:
ginger nut
'biscuit' is the definition.
(I've seen this before)
'one turned over in the midst of turning out' is the wordplay.
I cannot quite see how this works, but
'one' could be 'er' (I've seen this in other clues) and 'er' is located in the answer.
'in' is present in the answer.
'the' could be 't' (the is pronounced as a 't' sound in some dialects) and 't' is found in the answer.
This explanation may well be incorrect...
'for' acts as a link.
(Other definitions for ginger nut that I've seen before include "Type of biscuit" , "Spicy biscuit" , "Variety of biscuit" , "Kind of biscuit" , "redhead?" .)
