Horseradish

About Horseradish

The pungent root contains sinigrin, which converts to allyl isothiocyanate when grated - the same compound that makes mustard and wasabi hot. The heat is volatile and dissipates quickly, which is why prepared horseradish loses potency over time. It has been used for 3,000+ years, mentioned in Greek mythology. It is a powerful antimicrobial - traditionally used to preserve meat. It clears sinuses more effectively than many decongestants. It grows aggressively from any root fragment left in soil. It is a perennial that can be harvested year-round. It is essential for Passover seders. Over 90% of US horseradish is grown near Collinsville, Illinois.
