We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
I made my own last week. MUCH better than store-bought. Don't bother to grate it; the blender is a much better and labor-saving method. The finer the blend, the more irritating, so eye protection works. Add water until the consistency is to your taste, add salt ditto, then when the pungency is satisfactory, a teaspoon or two of vinegar to fix it.
I grew horseradish (in Ohio) for a while, peeled the roots, and grated it with salt and a little vinegar. Had to wear a bandanna over my face, and boy, was that stuff strong! Also, the roots go deep, so if you plant a patch, plan to keep it there forever.
oh boy! I love horseradish. Was able to grow it for years with very little attention being given to it. Planted it on the slope of a hill which seldom got watered. Bought new plant at the nursery and planted it on the top of the hill. Watered it, weeded it, etc. Cows ate it and it never came back.
