You really need to work the salt very well into the rind.

So I have put in a little piece of board and ye can work the salt in yourself.

His father, who makes Tuareg jewellery, used to work the salt caravans that ran between Timbuktu and Taoudenni.

It can be quite cathartic having to work the salt into the shredded leaves and then packing it all into jars.
