What is Horseradish?
Horseradish is a condiment that can be found in many forms including grated, powder, or pickled, and is used to make a number of sauces and dressings. Horseradish grows underground and is a close relative of mustard and wasabi.
The root is the part of the plant most commonly harvested but the leaves can be sauced or used in salads.
The Horseradish plant comes from Russia and is hungry and is even referenced in Greek mythology as well as Shakespeare. If you want to learn more fun facts about horseradish check out this article from Spruce Eats.
Grating Fresh Horseradish
Just a friendly PSA warning, when grating fresh horseradish with a box grater or food processor is prepared for quite strong fumes to come off the root.
Enough to make dicing onions seem like feather tickles.
The finer you grate the horseradish the stronger the fumes so if you are grating it for steak use the thickest setting on the box grater to minimize.
Definitely grate large amounts of horseradish in a well-ventilated area (outside even) and please not around small children.
Especially for a recipe like this, there is no shame in using prepared Horseradish. It’s convenient and there’s no need to cry over condiment making.
Whats the Difference Between Mayonnaise and Aioli?
About $5 bucks on a restaurant menu LOL. But seriously, Both mayonnaise and aioli are just an emulsion of eggs and oil.
Classically an aioli would be made with garlic and lemon but nowadays the lines of culinary liberties have blurred to the point where any flavored mayonnaise can be called an aioli.
So to give you a simple answer aioli is just a fancy word for flavored mayonnaise to impress your friends or charge extra at a restaurant. And I should know, I’ve been writing restaurant menus for 20 years.
