Supermarket after things with squashed flies in the middle for biscuit (9)
I believe the answer is:
garibaldi
'for biscuit' is the definition.
(I've seen this before)
'supermarket after things with squashed flies in the middle' is the wordplay.
I cannot quite see how this works, but
'supermarket' could be 'aldi' (Aldi is a supermarket chain) and 'aldi' 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 garibaldi that I've seen before include "Famous Italian" , "hero in Italy" , "Currant biscuit - Italian patriot" , "Italian leader; biscuit" , "Revolutionary leader" .)
