Display some ingredients of garibaldi - or a macaroon (7)
I believe the answer is:
diorama
'display' is the definition.
(type of display or model)
'some ingredients of garibaldi or a macaroon' is the wordplay.
'some ingredients of' indicates the answer is hidden within the clue (I've seen 'ingredient of' mean this).
'DIORAMA' can be found hidden inside 'garibaldi or a macaroon'.
(Other definitions for diorama that I've seen before include "Model representing a scene with three-dimensional figures" , "display" , "museum feature" , "Model showing a scene" , "Scene with models" .)
