How To Preserve Horseradish

In this brief guide, we are going to answer the question “How to preserve horseradish?”, and discuss the different methods of preserving horseradish and the potential implications of preserving horseradish.

How To Preserve Horseradish

You can preserve horseradish by freezing them as it really works well,  canning it by making a paste, and pickling it. Preserving horseradish is of great importance as it acts as an amazing condiment in the kitchen. It adds to the flavor and enhances the taste of the dish so prepared. 

Historic areas of U.S production include Illinois, Wisconsin, California (northern), Oregon and New Jersey, wh annually. Northere 3,500 to 4,000 acres are harvested temperate regions of the United States are found to be more suitable for production of horseradish and can often grow wild in areas with high soil moisture. Illinois being the highest producer of horseradish in the U.S supplies over 50% of American demand, with the majority of them being processed for the commercial condiment industry (1).

Freezing Horseradish

Freezing horseradish is one of the ways to preserve it and it works really well. Freezing is a popular method for extending shelf-life of a product and it influences composition and activity of plants (6). It is one of the easiest ways to solve the problem of storage and spoilage. Small chunks of cut horseradish roots can be frozen and stored in a freezer for up to six months, and then ground for use as needed. Prepared horseradish is most often preserved in vinegar and salt, but it is also available containing numerous other ingredients, such as mustard or mayonnaise-based spreads (3). Freezing horseradish involves the following steps: 

Step 1: Peel the skin off the horseradish using a sharp paring knife.

Step 2: Grate the horseradish with a fine cheese or vegetable grater.

Step 3: Line a cookie sheet with wax paper.

Step 4: Scoop the horseradish up with a tablespoon and place it on the cookie sheet in equal piles.

Step 5: Freeze the tray of horseradish piles overnight.

Step 6: Remove the frozen horseradish piles from the cookie sheet. Put them in a freezer bag and return them to the freezer.

In a study, among preservation methods studied, freezing at -20°C (-4°F) could retain more antioxidant capacity of horseradish than freeze-drying and microwave-vacuum-dried (6).

Another alternative to freezing horseradish is by following these steps (5):

Step 1: Peel and grate the horseradish using a sharp knife and vegetable grater. Grate 2 cups of horseradish.

Step 2: Add 1/2 cup of vinegar to the horseradish. White vinegar is fine but rice or apple cider also works.

Step 3: Add a bit of salt to the horseradish. The amount depends on your personal taste. Start with 1/2 tsp.

Step 4: Pour the mixture into clean, glass jars with tight sealing lids. Store in the fridge.

 Lemon juice can be used as an alternative to vinegar when preserving horseradish.

Pickled Horseradish Sauce (aka Horseradish Relish or Prepared Horseradish) (3)

  • 2 cups (3/4 pound) freshly grated horseradish
  • 1 cup white vinegar (5%)
  • 1/2 teaspoon canning or pickling salt
  • 1/4 teaspoon powdered ascorbic acid

Yield: About two half-pints


The pungency of fresh horseradish fades within one to two months, even when refrigerated. Therefore the steps involved are as follows:

  • Make only small quantities of the pickle at a time.
  • First, start with clean counters and utensils.
  • Wash hands for 20 seconds and dry with a single-use paper towel. 
  • Wash and scrub horseradish roots thoroughly with a clean vegetable brush. 
  • Peel off the brown outer skin of the horseradish.
  • The peeled roots may be grated in a food processor or cut into small cubes and put through a food grinder. 
  • Combine ingredients and fill them into sterile jars, leaving 1/4-inch headspace.
  • Seal jars tightly and store them in a refrigerator.

The pungency of fresh horseradish fades within 1 to 2 months, even when refrigerated. Therefore, make only small quantities at a time (3).

Horseradish roots are still used for pickling pears in some parts of Albania, and horseradish-infused pickled pears can store safely for 6 to 8 months, with the pickled pear juice used as a hangover remedy (4).

Canning of horseradish

Canning is another such method used for the preservation of horseradish as it is done for carrots. This enables storage of the horseradish for a longer period of time. The canned horseradish can be incorporated in various delicacies. 

The first objective in the process of canning is to preserve foods against spoilage. The second purpose is the preservation of food nutrients, and a third purpose is to retain natural food flavors and texture as far as is possible (2).

The quality of vegetable products depends on many factors, the main of which are: adherence to technological work in the preparation of raw materials for processing: the composition of spices added to the product: the order and mode of transition of technological processes compliance: the type of container in which the finished product is placed, its condition and the quality of preparation. Also, in order to obtain a high-quality processed product, the raw materials must have the same degree of maturity, color and size. Natural canned vegetables preserve the taste and aroma of vegetables, especially vitamins. These cans (in liquid form) contain 10-20 mg% of vitamin C, especially in green peas and 25-30 mg% in cauliflower (7).

  There are various tools required to can the horseradish. Tools required in the process are as follows:

  • Spade
  • Scratcher or scrub brush
  • Potato peeler
  • Knife
  • Spatula
  • Small jars
  • Bullet, ninja, or some grinding tool
  • Horseradish root
  • White distilled vinegar

The steps  that need to be followed in order to can the horseradish are as follows:

  • Cut off the top of the horseradish plant.
  • Wash the root in clear water, scrubbing it with a scratcher or scrub brush.
  • After peeling the root, cut them into small chunks. At this point, one will find that the root gets starting to get pungent.
  • Blend the horseradish using a blender.
  • Add a couple of inches of vinegar to the bottom of the grinding instrument and then add the root.
  •  If it is too runny add more root, if it is too dry add more vinegar.
  • Be careful to be stingy with the vinegar, as it can always be added if more is needed.
  • Fill the jars, leaving about 1/2 inch headspace. 
  • Put the lids on, but do not tighten them down.
  •  Place the so processed horseradish in the freezer or in a dark, cold place. 
  •  After they are fully frozen, tighten down the lid. 
  • These travel well and refreeze without loss of flavor or quality. 
  • While traveling, place the jars in a vacuum bag, primarily to be sure they don’t get water in them from the cooler.

Now, horseradish is ready to be used for the whole season in various food made.
