Amazing horseradish mustard recipe is very easy to make. My secret to the best horseradish mustard recipe is using moonshine, aka, white lightening! You may omit the moonshine and use vinegar and water if you prefer.
Horseradish mustard can be fermented and then dehydrated and ground into a powder to last for a very long time. Try growing a root or two for next year!

Where Can You Buy Horseradish Root?

Believe it or not, I bought my fresh horseradish root from Amazon, twice! I planted one root and the other I made this awesome horseradish mustard recipe. Check your local farm stores and all-natural stores to see if they carry fresh horseradish root.
Do You Need to Soak Mustard Seeds?

There are many recipes that will require you to pre-soak your mustard seeds. I do not soak my mustard seeds; I personally do not find a need for that. My process will make the seeds just as soft as if you pre-soak them. I have to say horseradish mustard made with moonshine is by far, my favorite!

How to Make Horseradish Mustard
Please feel free to modify this recipe to your own liking. You may like more vinegar, more or less horseradish or no moonshine to be replaced with water and or vinegar.
I like to ferment mine for 3 to 5 days by allowing the horseradish mustard to sit on the counter once all the ingredients are incorporated. You do not have to ferment yours, but honestly, I believe the taste is more pungent by fermenting them first.
Preparations for Making Horseradish Mustard Recipe

Fresh horseradish that has been picked from the garden or purchased should be washed, peeled, and shredded. If you prefer dicing over shredding, make sure to cut the horseradish into very small pieces. My favorite method of shredding horseradish is to cut 1-2-inch pieces into the blender and pulse until very finely ground.
You may want to increase the horseradish if you like it really hot, this recipe is semi-hot but not too hot for the average person.
Save those peels for the compost bin. If you would like to know more about Making Compost Naturally into Garden Soil, check out the blog for more information.

Horseradish Mustard Fermenting Instructions

- Add a fermenting silicone lid
- Place on the counter for 3 to 5 days to begin the fermenting process (less if it is above 75 in your home)
- If you do not have a fermenting lid put on a regular plastic canning jar lid very loosely
After 3 to 5 days, remove the fermenting silicone lid and replace it with a regular metal canning jar lid or a plastic canning jar lid and store it in the fridge.
If you do not want to ferment the horseradish mustard, place the jars immediately in the refrigerator with regular lids and enjoy!
Dehydrating Horseradish Mustard

I prefer to dehydrate my horseradish mustard. I cannot use a quart of horseradish mustard in a reasonable amount of time before it spoils.
Dehydrated mustard will last longer than wet mustard that is in the refrigerator. There are many ways to use dehydrated mustard too. One of my favorite ways is to add a tablespoon to my Buttermilk Wheat Rolls in the Breadmachine for making hotdog buns, stop by that blog post for more information and a PDF printable recipe.
Another reason why I dehydrate my mustard is I do not like my buns getting soggy from ketchup and mustard. The dehydrated mustard also cuts down on the wetness when Iβm making deviled eggs, potato salad, and other recipes.

In Conclusion on Horseradish Mustard
Our family has always enjoyed horseradish mustard on a lot of things. We enjoy making it even more. As we evolve over the years, we seem to tweak, change, and try new things. Fermented horseradish is a game-changer but you can forgo that and not ferment. But we think that once you try fermenting, you’ll be hooked like us!
