Biscuit to break the French spirit first? (6,4)
I believe the answer is:
brandy snap
'biscuit' is the definition.
(type of biscuit)
'break the french spirit first?' is the wordplay.
'break' becomes 'snap' (snapping is a kind of breaking).
'the french spirit' becomes 'brandy' (alcoholic spirit often made in France).
'first?' is a charade indicator (letters next to each other).
'snap' put after 'brandy' is 'BRANDY-SNAP'.
'to' is the link.
(Other definitions for brandy snap that I've seen before include "Crisp ginger biscuit" , "Crisp, rolled biscuit" , "Cream-filled gingerbread wafer" , "Cookie" , "Crisp confection" .)
