It’s of consuming interest if you’re thinking of an apple (7)
I believe the answer is:
strudel
'apple' is the definition.
The definition and answer can be both things that one consumes for nourishment as well as being singular nouns.
Perhaps there's a link between them I don't understand?
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for strudel that I've seen before include "German pie" , "Baked dish" , "Germany pastry" , "Fruit-filled pastry from Austria" , "German dessert" .)
