I'm back home and I wanted to prepare erythrean panckes. I don't have the recipe but internet... so I found out that it is called "injera". And I discovered the world cook book from the FAO (INPHO). It's really interesting for traditional and local recipes. Here is the link: http://www.fao.org/inpho/isma?difficulty=&m=cookbook&i=INPhO&commodities=&grp_com=2&p=AdvancedSearchForm&dish_type=7〈=en
It's not super user friendly but if as my mum you buy cereals at the asian shop and don't know what you could do with it, it can be helpful to find a dish with your ingredient. And they are no fancy recipes as most of them were studied from a nutritional point of view and are collected to help population to save the diversity of cooking.
