Horseradish
Horseradish is believed to be native to Russia or Hungary. It is related to the mustard family, thus its biting flavor and aroma. The "horse" moniker refers to the size of the root as well as its pungency and was used to distinguish it from other radishes. At one time, horseradish was referred to as "German mustard."
Used for thousands of years, horseradish is one of the five symbolic bitter herbs celebrated in the Jewish Passover Seder.
The mustard-like oil in horseradish is the element that can bring tears to the eyes much like onions do, as well as the feeling of heat on your tongue. Like mustard, the heat and fumes rapidly deteriorate once the horseradish is cut or grated and exposed to air. Heat eliminates both aroma and the heat, which is why true horseradish lovers prefer horseradish raw and freshly grated.
The bite and aroma of the horseradish root are almost absent until it is grated or ground. During this process, as the root cells are crushed, volatile oils known as isothiocyanates are released. Vinegar stops this reaction, stabilizes the flavor and locks in the heat.
In one tablespoon of prepared horseradish, there is only 6 calories , 1.4 grams of carbohydrates, 14 milligrams of sodium, 44 milligrams of potassium, 9 milligrams of calcium, 5 milligrams of phosphorous AND ZERO FAT.
Horseradish root has antiseptic and stimulant properties, plus can aid in digesting rich and oily foods. Some people mix a little horseradish into salads, believing it wards off colds and chills and gets rid of persistent coughs. What gives it this kick? A glycoside called sinigrin that releases horseradish's acrid sulfur bearing oil through enzymatic action. But continued heat reduces the pungency dramatically. It should always be added at the end of cooking at a low temperature.
If you are trying to lose weight, make sure horseradish, mustard and salsa are on your shopping list, advises recent guidelines on obesity from the National Heart, Lung, and Blood Institute (NHLBI).
