Bread and sugar (4)
I believe the answer is:
loaf
I believe this clue is a double definition.
'bread' is the first definition.
(loaf is a kind of bread)
'sugar' is the second definition.
(loaf sugar is a kind of sugar)
'and' acts as a link.
(Other definitions for loaf that I've seen before include "Hang around for bread?" , "Idle - head" , "Bread - brain!" , "Spend time idly, having slang head" , "Head - bread" .)
