Here in Coventry (in the English midlands) we call a bread roll a "batch".
It seems to come from the same root as "bake" (or batch production) and I believe it also appears in the King James bible as the "batch of life".
We even had a "Batch bar" (a sort of sandwich shop, but using batches instead of sliced bread) just round the corner from us for many years.
I've always considered batch to be a Coventry oddity since I've never come across it being used anywhere else. Is that true?
