Piper guineense is a West African species of Piper; the spice derived from its dried fruit is known as Ashanti pepper, Benin pepper, Edo pepper, false cubeb, Guinea cubeb, and called locally kale, kukauabe, masoro, etiñkeni, sasema, soro wisa, eyendo, eshasha by the Urhobo people, and oziza and uziza by the Igbo people of Nigeria. It is a close relative of cubeb pepper and a relative of black pepper and long pepper. Unlike cubeb, which is large and spherical in shape, Ashanti pepper grains are prolate spheroids, smaller and smoother than Cubeb pepper in appearance and generally bear a reddish tinge. The stalks of Ashanti pepper berries are also distinctly curved whilst those of cubeb pepper are completely straight. The terms West African pepper and Guinea pepper have also been used, but are ambiguous and may refer to grains of Selim or grains of paradise.
In terms of flavour, Ashanti pepper is very similar to cubeb pepper but is less bitter and has a fresher, more herbaceous flavor and aroma than cubeb's more pine-like scent. Though known in Europe during the Middle Ages (it was a common spice in Rouen and Dieppe in 14th-century France), these days, its use is largely restricted to West and Central Africa.
