Lifestyles Ideas Management - Wasabi

Powdered wasabi in a tin or wasabi paste in a tube aren’t the real thing. They are made with Western horseradish plus food coloring.
True wasabi toot is finicky to grow and process, requiring very clean water.
This means that growers make much ado about their precious crop, which is generally available at local Japanese supermarkets only as seasonal and expensive fresh whole root. It also means that only the most expensive sushi bars will serve you real, grate-it-yourself wasabi. All other establishments here and in Japan rely on the car more economical but far more sledgehammer to the sinuses colored horseradish.
Mustard, wasabi and horseradish are all members of the Brassica plant family. They all get their pungency from compounds called isothiocyanates that are formed when the relevant parts of the plants are bruised, heated or hydrated. Flavor-wise, they are not truly interchangeable. Wasabi has the most subtle character, combining sweet, floral nuances of aroma with a clean, biting heat. It is unquestionably best eaten raw and freshly grated because it loses vibrancy quickly as it stands. Serve it with compatible ingredients such as seafood and young vegetables. Mustard seeds have many different faces. They can be “popped” in hot cooking oil for a nutty warmth, pressed to release their own sharply pungent, heady oil or ground with vinegar, wine, water or other liquids to yield condiments of widely varying intensity.
For marinades, choose a strong mustard condiment, like English mustard or Japanese Karashi mustard, or make your own with mustard powder and cold water.
Horseradish root, like wasabi should be grated and eaten right away. It gets bitter and loses heat and complexity as it stands through mixing it with an acidic ingredient like vinegar slows this down somewhat.
It has a fierce, throat tickling heat that best partners other assertive flavors such as red meat and oily fish. Ask The Foodie Chris Tan.
