Nuts

Shell

The shea nut shell is the hard protective layer around the kernel of the seed of Vitellaria paradoxa from African savannah parklands. It is not a primary food, but it governs storage life, in-shell roasting, and how nuts move through trade. Home cooks crack shells for peak freshness; factories crack and aspirate them before packing kernels. Shell fragments are a dental hazard—inspect home-cracked meats carefully. Clean shells may be composted or used as biomass; never assume every shell is edible or safe to smoke food with. Species home range: West and Central African shea belt. Edible value lives in the kernel, whose flavour is shea butter for food is mild and fatty; much global shea is cosmetic, but edible grades exist in regional cooking. Specify edible vs cosmetic shea for kitchen use; not all retail shea is sold as food. Shell hardness influences whether retail sells in-shell product at all. Keep shell grit out of flour mills and blenders. Sound in-shell lots often keep longer than warm shelled kernels because the shell limits oxygen.
