Roll made by first two in bakery on rising (5)
I believe the answer is:
bagel
'roll' is the definition.
(bagel is a kind of roll)
'first two in bakery on rising' is the wordplay.
'first two in bakery' becomes 'ba' (I am not sure about this - if you are sure you should believe this answer much more).
'on' becomes 'leg' (cricket term, fielding positions).
'rising' is a reversal indicator (going up in a down clue).
'leg' back-to-front is 'gel'.
'ba'+'gel'='BAGEL'
'made by' acts as a link.
(Other definitions for bagel that I've seen before include "Doughnut-shaped bread roll" , "It's edible" , "round fare" , "Ring-shaped bread product" , "Ring-shaped bread roll" .)
