That lot at the bakery (5)

I believe the answer is:
batch
'that lot' is the definition.
(synonyms)
'at the bakery' is the wordplay.
I cannot really understand how this works, but
'at' is present in the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for batch that I've seen before include "Aggregation" , "Set, collection" , "Lot made at one time" , "Production quantity" , "A number of things produced at the same time" .)
