Horseradish
Armoracia rusticana
Similar to the wasabi, horseradish is a long true root that grows more like burdock (Asteraceae) than it grows like a radish. It’s particular flavor of punch-you-up-the-nose heat is rather blunt and immediate with less complicated flavors than wasabi is known for. Due to wasabi’s limited growing conditions and the ease with which horseradish grows, most of the wasabi paste we eat with our sushi is mostly horseradish and green food coloring. Regardless of which one is getting your sinuses dripping, it’s clear that these two Brassicas bring the heat like no others.
