I am a horseradish fan. None of those horseradish cream, dips etc are the equal of a great home made horseradish. Let's get the basics.
The finer you can grate your horseradish root the hotter it will be. I use a thermomix to chop/grate. It makes it exceedingly fine. Then I add a couple of pinches of salt (to taste) and a slosh of white wine vinegar - just enough to moisten the horseradish. That is it - ready to use - hot & flavoursome. If you are a wimp add some sour cream to tone down the heat!
When you stop horsing around it is time to fire up the BBQ & Smoker
