Order a dessert (5,3)
I believe the answer is:
apple pie
I believe this is a double definition.
'order' is the first definition.
(I have seen 'such order' mean 'apple pie' so perhaps 'order' could also mean 'apple pie')
'a dessert' is the second definition.
(I have seen 'Common dessert ' mean 'apple-pie' so perhaps 'dessert' could also mean 'apple-pie')
(Other definitions for apple pie that I've seen before include "Dessert - kind of bed or order" , "Sweet (in good order?)" , "tarte Tatin, for example" , "(Characteristically American) sweet" , "Tasty pastry" .)
