G'day Again. Sorry for this long post but thought you might find it interesting. For the people who are discussing the hotties - Wasabi + Horseradish , well they are not the same thing - Related but not the same. Same family but different Genus and Species. See below; W A S A B I (Wasabia japonica syn. Eutrema japonica) is a member of the cruciferae family originating in Japan and is related to cabbages. It is a perennial which grows about knee high, is semi aquatic and produces a thickened stem in a similar fashion to a small brussel sprout. As the stem grows the lower leaves fall off. This stem has a very pungent smell and flavour when made into a paste. Wasabi can be produced both as a ground grown or water grown plant. The water grown plants produce a higher quality product than the ground grown plants. http://www.wasabi.co.nz/meet.html ============= Horseradish Botanical:Cochlearia Armoracia (LINN.) Family: N.O. Cruciferae This plant has been in cultivation from the earliest times, but its exact place of origin seems to be obscure. Hooker considers that it is possibly a cultivated form of Cochlearia macrocarpa, a native of Hungary; other authorities consider it indigenous to the eastern parts of Europe, from the Caspian and through Russia and Poland to Finland. In Britain and other parts of Europe from Sicily northwards, it occurs cultivated, or semi-wild as a garden escape. It is probably the plant mentioned by Pliny under the name of Amoracia, and recommended by him for its medicinal qualities, being then apparently employed exclusively in physic, not as food or condiment It is possible that the Wild Radish, or Raphanos agrios of the Greeks was this plant It is said to be one of the five bitter herbs, with Coriander, Horehound, Lettuce and Nettle. which the Jews were made to eat during the Feast of Passover. http://www.botanical.com/botanical/mgmh/h/horrad38.html Regards Mark E. in Melbourne
