I live in London and have a food recipe to preserve in a bottle. Does anyone know where I can get a short training in food preservation/bottling for say one day or a few hours?

You could also check out youtube as there are loads of videos on the subject. In North America we call bottling as canning so you'll find it under that title.

Thanks for sharing these links - have just contacted the food safari people for dates as sounds very interesting.

You're welcome. A google brought back loads of results, but the OP asked for London so I only posted a couple.
