This order is typically American! (5,3)
I believe the answer is:
apple pie
'this order' is the definition.
(I have seen 'such order' mean 'apple pie' so perhaps 'order' could also mean 'apple pie')
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for apple pie that I've seen before include "fruit tart" , "tarte Tatin, for example" , "Fruit dessert (with order suggesting perfection?)" , "in a virtuous form?" , "(Characteristically American) sweet" .)
