Roll container Errol emptied (5)
I believe the answer is:
bagel
'roll' is the definition.
(bagel is a type of roll)
'container errol emptied' is the wordplay.
'container' becomes 'bag' (bag is a kind of container).
'emptied' means to remove the middle letters.
'errol' with its centre removed is 'el'.
'bag'+'el'='BAGEL'
(Other definitions for bagel that I've seen before include "Hard bread roll in shape of ring" , "round fare" , "Ring-shaped bread product" , "Doughnut-shaped bread roll" , "Toroidal bread roll" .)
