This summer I ran out of horseradish and was eager to get more but it is better to harvest in the fall so I needed to wait. Actually I read later that it is best to harvest after frost (I think it increases the potency of it) but we did harvest before that though I might go back now that it is frosted and get some more sometime.
With horseradish you want the root. I loosened up the soil around the plant with a potato fork and then I gently pulled and got out as much of the root as I was able. The horseradish had grown mixed in with my parents potatoes so we were able to dig both at once. The roots can often be long, twisted and skinny but we did the best we could.
I let it grind up as little as it would and then I put it in a jar and am storing it in the fridge. I am glad to have a supply of horseradish on hand again!
When my sister processed some I took to her she did do it (in her blender) inside but she had the blender right under her fan/vent.
Do you process your own horseradish? Do you do anything different? I would love to have you add your thoughts or tips! Also - what do you all like to use horseradish for?
