Crinkled aluminium sheet used while making pastry (4)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
filo
'pastry' is the definition.
(I know that filo is a type of puff pastry)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for filo that I've seen before include "Pastry used for baklava" , "Pastry made in thin sheets" , "A type of very thin pastry" , "Kind of pastry" , "Thin flaky pastry" .)
