If you buy ground Nigerian food ingredients: egusi, ogbono, crayfish from African food shops, the video below is a must see for you. The points made in the video is exactly why I do not buy ground Nigerian food ingredients from African food shops. Yes, it’s a lot of work to grind these myself but until the distributors of these ingredients start applying health and safety to their food handling, I will be doing the grinding myself or at least sort them myself before going to grind with the heavy duty grinders in Nigerian markets.
With just my ever reliable spice grinder, I am good to go.
