How a batch gets its number
Every jar has a batch number on the label. Here is what it tells you and why we bother.

Every label carries a batch number. It counts how many times we have cooked that recipe, so batch 14 of the damson chutney is the fourteenth time, starting in autumn 2022.
It began as a way to remember which pot had burnt. It is now the quickest way for a customer to tell us a jar tasted different: send the number and we can find our notes.
We write down the cooking date, the pot, the weather in the kitchen and who stirred. Nobody has ever asked for the weather. We keep writing it down anyway.
