Dessert or kind of bed that prevents you going straight to sleep (5,3)
I believe the answer is:
apple pie
'dessert' is the definition.
(I have seen 'Common dessert ' mean 'apple-pie' so perhaps 'dessert' could also mean 'apple-pie')
I don't understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for apple pie that I've seen before include "Dessert - kind of bed or order" , "Perfect order - bed jokily made" , "Tasty pastry" , "in a virtuous form?" , "(Characteristically American) sweet" .)
