Mustard

The plants that produce mustard seeds are various and belong to different species. This means that, in truth, the term "mustard" represents a lexical simplification and totally ignores the botanical nature of the plants in question.
These are herbaceous plants belonging to the Brassicaceae family and the Brassica genus, but which are quite different in terms of the overall appearance, the shape and color of the seeds, as well as the organoleptic characteristics of the latter.
Black mustard orB. nigrais large in size. The first finds documenting its use place it mainly near the area surrounding Egypt, of which it appears to be native. It produces small black berries, with a strong and decisive taste. In contrast,B. albais modest in size; typical of the Mediterranean basin, today it is also widely spread in the American continent. It has large, yellow and not very spicy seeds; it is called white mustard in Europe or yellow mustard in the USA.
