Perforated bowl (8)
I believe the answer is:
colander
'perforated bowl' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for colander that I've seen before include "Device for straining water from food" , "Kitchen strainer" , "Utensil for draining vegetables" , "Boiled 20 Down may be strained through this" , "Kitchen sieve" .)
