What is horseradish?
Horseradish is actually a root vegetable and looks most similar to ginger when whole. It gives a unique heat that gives you a punch of flavor that quickly wears off. Most people don’t get the whole root, which needs to be grated or shredded. Instead they use prepared horseradish which is grated horseradish root suspended in vinegar.
However, you like a super pugenet horseradish, do yourself a favor and find a fresh root. The older the root and the longer it has been grated, the less tasty it will be. It also loses flavor when cooked.
They can be easily peeled with a Y peeler, vegetable peeler or sharp knife. From there either grate or finely mince.
It comes from the same family as wasabi and mustard. And like these two, the flavor can vary greatly from plant to plant. Here are substitutions for horseradish.

Perfect Pairings
Aioli is excellent as a dipping sauces or condiment to slather on sandwiches or burgers. It can be used on all sorts of sandwiches, but I love it on Steak Sandwiches. You can dip olives, carrots or potato chips and even put a dollop on top of cooked veggies or crab cakes.
It also tastes great on anything from prime rib, roast beef sandwiches, steak bites, crab cakes, shrimp, smoked salmon and oysters to roasted potatoes, asparagus, sweet potato fries and veggie platters.
Frequently Asked Questions
Prepared is grated horseradish in vinegar; it’s convenient and stable. Fresh is hotter but less consistent—if using, start small and add to taste.
For spicier, add more drained horseradish or a pinch of cayenne; for milder, add more mayo and a squeeze of lemon.
You of course can, but we always recommend fresh lemon juice. Any citrus juice starts to lose flavor as soon as it is harvested. Fresh juice has much more flavor than jarred and without any preservatives.
