Here you go !
Take one horseradish root recipe is not size specific.
1 Cup Vinegar
1/ cup Sugar
Peel root down to the white, then cube it up fairly small.
Put in a food processor with a little vinegar to blend easier.Blend to as smooth as possible.
* Do Not Stick Your Head Over It To Smell How Good It Is Or They Will Be Picking You Up Off The Ground * ( Even Better If You Can Process It Outdoors.)
Heat up the rest on the vinegar and Sugar to a boil add a pinch of salt, Take off the stove and add the blended horseradish. And Cool in fridge.
Add Sour Cream or Creme fresh to make creamy if you like it that way.
I dont like any store bought after having it like this. Let me know if you try it.
