Arts graduate turns to jelly and bread rolls (6)
I believe the answer is:
bagels
'bread rolls' is the definition.
'arts graduate turns to jelly' is the wordplay.
'arts graduate' becomes 'ba' (Bachelor of Arts).
'turns to jelly' becomes 'gels'.
'ba'+'gels'='BAGELS'
'and' is the link.
(Other definitions for bagels that I've seen before include "Doughnut-shaped roll with hard crust" , "Ring-shaped bread rolls" , "Hard ring-shaped rolls" , "Jewish bread rolls" , "Doughnut-shaped bread rolls" .)
