John really enjoys his ‘gator,’ riding around the property and checking on the different plantings. This weekend the horseradish was in bloom. What an interesting plant…a member of the Brassicaceae family and a relative to plants such as mustard, broccoli, kale, and radishes. It is cultivated for its thick, fleshy white roots.
The “hotness” from horseradish comes from isothiocyanate, a volatile compound that, when oxidized by air and saliva, generates the “heat” that some people claim clears out their sinuses. 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, isothiocyanates are released. Vinegar stops this reaction and stabilizes the flavor. For milder horseradish, vinegar is added immediately.
