As baked at some stage in experimental labs? (6)
I believe the answer is:
bagels
'as baked at some' is the definition.
I can't judge whether this defines the answer.
'stage in experimental labs?' is the wordplay.
'stage' becomes 'ge' (I can't justify this - if you can you should give a lot more credence to this answer).
'in' is an insertion indicator.
'experimental' indicates anagramming the letters.
'labs' with letters rearranged gives 'bals'.
'ge' placed into 'bals' is 'BAGELS'.
Can you help me to learn more?
(Other definitions for bagels that I've seen before include "Doughnut-shaped roll with hard crust" , "Hard ring-shaped rolls" , "Doughnut-shaped bread rolls" , "Ring-shaped bread rolls" , "Jewish bread rolls" .)
