Key Areas Covered
What is Horseradish
Horseradish is a spicy root vegetable that belongs to the family of mustard. It has long green leaves and is cultivated for its long white root. Importantly, horseradish is usually cultivated in cold environments. It is an aromatic vegetable and has also been used as a medicine over the centuries around the world. Especially, horseradish consists of a chemical composition called sinigrin, which helps to reduce swelling by blocking or changing the parts of the immune system that cause the swelling.
Concerning the uses, people use horseradish to make a sauce, and it is available in pre-packs. You can use this sauce as a dip for fish sticks and as a substitute for mayonnaise. In addition, you can add it to mashed potatoes to give them a spicy flavor. This sauce is also useful as a dressing for steak. Meanwhile, people also use freshly grated horseradish for vegetables and meat dishes.
What is Wasabi
The wasabi plant belongs to the family Brassicaceae. The flavor of wasabi is quite similar to horseradish and radish. Stems and rhizomes of this plant are mainly used for cuisine. Real wasabi is very expensive. In fact, wasabi has become one of the most expensive spices on the market. Thus, several cheap substitutes are available in the market with artificial coloring. Wasabi is hard to grow because we need to partially submerge it in moving water. In Japan, wild wasabi grows on rocky surfaces and in riverbeds. But these plants are not good at survival because even minute climate changes can cause their death.
We also use the name wasabi for the pungent, green paste or spice that we make using these plants. Wasabi paste serves as a condiment to dishes like sushi. Making the wasabi paste involves grating the stem. But the flavor of the paste may disappear within fifteen minutes if the paste is not covered. Wasabi paste enhances the flavor of pork and other meats. Freshly grated wasabi also gives a marvelous taste to any dish. The flavor of wasabi can increase the taste of raw fish and helps to highlight the flavor of the fish.
