On vacation, repeatedly exasperating guests before noon order such dish (4,8)
I believe the answer is:
eggs benedict
'dish' is the definition.
(eggs Benedict is a kind of dish)
'on vacation repeatedly exasperating guests before noon order' is the wordplay.
I cannot quite understand how this works, but
'noon' could be 'n' and 'n' is found within the answer.
'order' could be 'edict' ('edict' can be a synonym of 'order') and 'edict' is located in the answer.
This explanation may well be incorrect...
'such' acts as a link.
Can you help me to learn more?
(Other definitions for eggs benedict that I've seen before include "Dish with ham on toast" , "Dish served on toast" , "Breakfast dish with hollandaise sauce" , "snack" , "something for breakfast?" .)
