Freezing horseradish?

I make my own horseradish - very basic, just the grated root and white vinegar. It's delightfully powerful for a few days, but after a week or so it's still tasty but has lost that kick.

I can rarely use up a full batch before it fades away, so I'm thinking of preparing only half a root at a time and freezing the other half. My question is, should I freeze half the root, or grate the whole root and then freeze half the prepared paste? Has anyone got any experience with either of these methods?

  1. I have never frozen the root but I have bought prepared horseradish by the gallon from places that provide it to oysters bars--this ensures that the product moves fast and does not lose the "kick." I divide it up into little ziplock bags and freeze those---I farm them out to friends and we each get a dozen or so. I then thaw out a bag as needed. It does not have the punch of the fresh but it is far better than it would be had I left it sit in the icebox.

    1. Have never frozen horseradish but post got me thinking. I know "they" say you can freeze ginger and grate from frozen. Ginger and horseradish are both roots & not so expensive that a mad scientist experiment would be outta the question. Thinking freeze whole but peeled and ready to grate??

        You both have good suggestions - I think I'll pick up an extra root and do half each way, just to see what happens. I'll report back later.

          I'd freeze whole and grate frozen. Double wrap to combat freezer burn.

        2. I've been wondering about how to preserve horseradish too. I usually just buy it fresh at the market but I'd like to grown some. I've been thinking about trying dehydrating and lacto fermenting it. See which one might work better.

            rasputina - speaking from experience, DO NOT attempt to grow your own, unless you can do so in a closed container. Horseradish is one of the most invasive species in all of botany - and what's worse, it spreads by sending out thin brittle roots deep below the surface, and even a small fragment of those roots can start a new plant. It took over my plot in a community garden many years ago, and to eradicate it I had to dig up all the soil for a yard around it, at least 18" deep, and sift it all to get rid of the roots.

              eeekkk that sounds even more invasive than mint.
