Rustled up Austrian pudding (7)
I believe the answer is:
strudel
'austrian pudding' is the definition.
The definition and answer can be both things that one consumes for nourishment as well as being singular nouns.
Maybe you can see a link between them that I can't see?
'rustled up' is the wordplay.
'up' indicates anagramming the letters (letters get chucked up).
'rustled' is an anagram of 'STRUDEL'.
Can you help me to learn more?
(Other definitions for strudel that I've seen before include "German fruit-filled pastry" , "German pastry dish" , "Austrian fruit-filled pastry" , "Dessert of thin pastry filled with fruit" , "German pie" .)
