What Is Horseradish Mustard? [Uses, Taste & Recipe]

What Is Horseradish Mustard
Share on:

Horseradish mustard is a tangy, earthy, slightly bitter, and simply delightful condiment you can use on almost anything under the sun. I am absolutely head over heels for this condiment because it gives vibrancy even to the dullest of dishes, meaning that if I do something wrong while cooking, I can always cover it up!

Since it would be a shame to go through life not experiencing the delightful zing horseradish mustard gives your food, you absolutely must stay for this article. I will tell you all you need to know about horseradish mustard, and hopefully, you’ll enjoy it with your food as much as I am. 

How Is Horseradish Mustard Made?

Horseradish mustard is a type of mustard that combines the flavors of horseradish and mustard.

Making horseradish mustard is a piece of cake, and you can make it easily at home, as well as buy it ready-made. Horseradish mustard combines horseradish, either freshly grated or prepared, with mustard. You can find my recipe down below!

The mustard can come as mustard seeds or pre-prepared mustard. The ingredients are mixed together in the desired proportions and blended or stirred until homogenized. The seasoning can vary depending on the brand or your preference if you make it home. 

Still, horseradish mustard is very potent as it is, so you would not usually use strong additional spices when making it. 

Is It the Same Thing as Dijon?

Dijon Mustard vs. Horseradish Mustard

Horseradish mustard is in no way the same thing as Dijon mustard.

One of the most frequent mistakes people make when it comes to horseradish and Dijon is thinking that the two are one and the same. Dijon mustard comes from black or brown mustard seeds crushed into a powder and mixed with white wine or wine vinegar, water, and salt, while horseradish mustard contains horseradish and mustard (pre-made or seeds).

What Does Horseradish Mustard Taste Like?

Horseradish mustard harnesses the best of both worlds. What I find most fascinating about how mustard seeds and horseradish complement each other is that when had separately, they both tend to be overwhelmingly intense, yet together they balance each other out. Horseradish and mustard seeds bring out the best in each other. 

Horseradish mustard has a distinct, rich, and overall vibrant flavor. It combines the spicy and pungent heat of horseradish with the tanginess and sharpness of mustard. It is savory, bitter, slightly hot, and slightly sweet all the same time. 

The best thing about horseradish mustard is that the flavor is not only vibrant but very adaptable. So, when you add it to a particular food, it doesn’t take the lead, but it allows for the flavors to dance on your palate. 

Roast is my favorite place to use horseradish mustard. It intensifies the meatiness and juiciness of the roast, but it also adds its own magic to the meal. The spiciness of the horseradish gives the dish a very noticeable kick, while the mustard adds a tangy and sharp element to the overall taste.

Uses of Horseradish Mustard 

Since horseradish mustard is a condiment, you can use it anywhere to add more flavor. So, horseradish mustard fits perfectly in almost any setting, from sandwiches to roasts to salad dressings or dips and sauces

Horseradish mustard gives your dish a bold and zesty flavor, depth, and complexity, making it more colorful, no matter how simple the dish is. You can make a plain sandwich, and a smear of horseradish mustard will turn it into a zesty gourmet meal. 

Where to Buy Horseradish Mustard?

If there’s one thing bringing horseradish mustard as close to perfection as possible, in addition to its flavor, that is definitely its availability. I find it very frustrating when I can’t get a hold of something delicious, and I appreciate the fact that I can find horseradish mustard anywhere, anytime. 

Horseradish mustard is very available, and you can find it in most grocery stores, supermarkets, and specialty food stores. If you can’t find it at the store that is nearest to you, you will definitely find it at the next one. 

It is usually in the condiment aisle or the section dedicated to mustards and sauces, so you won’t miss it. Also, many online retailers and e-commerce platforms offer a wide range of horseradish mustard brands and varieties that can be conveniently purchased and delivered to your doorstep, so it can also be just a click away. 

Its Substitutes

Mustard and Horseradish Sauce

On the off chance that there isn’t any horseradish mustard at the time you need it, you can always substitute it for another condiment that will bring you certain aspects of its flavor. Before I go on, I must stress that no substitute will substitute for the entire flavor profile of horseradish mustard. 

Mustard and horseradish sauce is the best substitute for horseradish mustard. It brings the heat of the horseradish and the bitterness and tang of the mustard. Still, this combo is milder than actual horseradish mustard, so keep that in mind when determining how much you add to your food. Start by mixing equal parts of mustard and horseradish sauce and adjust the quantities according to your preferences. Add more horseradish sauce for extra heat or more mustard for a tangier flavor.

Mustard and grated horseradish is another way to go but be prepared for things to get expressively hot since fresh horseradish isn’t so gentle. Again, start by mixing equal parts of mustard and grated horseradish and tailor these amounts to your taste.

If you don’t have any horseradish or horseradish sauce around, spicy mustard varieties can do the trick. Brown mustard, or whole grain mustard, can give you a similar kick and depth of flavor as horseradish mustard, but you’ll have to give up the horseradish heat. Still, I have found that adding a pinch of black pepper can partially make up for the horseradish heat, so it is definitely worth a try. 

Recipe for the Best Homemade Horseradish Mustard Sauce

As I mentioned before, making horseradish mustard at home is a piece of cake, and the best thing is that you’ll have your cake and eat it, too, because there’s no way that this recipe won’t work. 

So, take a look below and enjoy your delicious horseradish mustard sauce! 

First, you’re going to need to prepare all the ingredients. You’ll need 1/4 cup yellow mustard seeds, 1/4 cup brown mustard seeds, 1/4 cup prepared horseradish, 1/4 cup white wine vinegar, 1 tablespoon honey, and 1/2 teaspoon salt.

Note*: If you don’t have both yellow and brown mustard seeds, you can use one or the other; just double its amount.

Note**: Prepared horseradish is grated horseradish mixed with honey, white vinegar, and salt. To prepare the horseradish, mix it with these ingredients and let it sit for about half an hour before you add it to the mustard seeds. 

Here’s how you can prepare it at home!

Step 1: Prepare the Mustard Seeds

Take out a bowl, and place in the yellow and brown mustard seeds. Then, you need to add water to cover the seeds, and let them soak for about 2 hours to soften. Make sure the water isn’t hot — I usually use lukewarm water, as it works perfectly.

Step 2: Blending the Ingredients

Now, drain the mustard seeds and put them in a blender or food processor. If you have both and can choose, pick the food processor. 

Here’s where you add the prepared horseradish to the blender. Simply blend the mixture until you achieve a smooth and creamy consistency. This is it!

The seasoning hasn’t been set in stone, so try your horseradish mustard sauce and tailor it to your preferences. I don’t like to use a lot of spices since the sauce is already very flavorful, so a pinch of salt is more than enough for me. 

Still, you can adjust the flavor as you like it best. Add seasoning or more horseradish for extra heat or honey for sweetness.

How to Store It?

Store the sauce in the refrigerator for at least a few hours, preferably overnight, to allow the flavors to meld and develop. If you eat the sauce right after making it, believe me, you won’t experience its full potential. 

In addition to refrigerating it overnight, you must store your horseradish mustard sauce in the fridge. Not only will it further develop flavor over time, but it will be safe to eat for up to two weeks. Just make sure you store it in an airtight container, and you’re done.
