Tiered display of piping at the match? (7,4)
I believe the answer is:
wedding cake
'match?' is the definition.
Although both the answer and definition are singular nouns, I don't understand how one could define the other.
I don't understand how the remainder of the clue works.
(Other definitions for wedding cake that I've seen before include "centrepiece at reception?" , "A winged deck (anag.)" , "Tiered confection" .)
