Here is a picture of the only High Holiday celebration in Mali:

Ari and Jess put together a Rosh Hashannah seder and got materials to do all the davening for the high holidays.
A couple years ago I walked about 10 miles each way to celebrate a Rosh Hashannah seder with Ari’s family when he was in the US. Their tradition traces to Tunis where it was common to have a meal with many food blessing-puns for a new year. It was neat to be included in this ritual. In an amazing turn of events it has been celebrated in Africa. Here is Ari’s beautiful account of the experience of spiritually preparing and cooking a feast without a sharp knife, counter, kitchen, oven, running water, or electricity.
