No problem! Please let us all know how they turn out!Just a word of caution - protect your eyes when grating old horseradish - it will burn your eyes. Use swimming goggles. I know people who didn't realize this until it was too late - they got a chemical burn, took a week to recover. Cheers!

Apparently it depends on when you add the vinegar for the degree of hotness. The recipe I found on the net said vitamize and then add the vinegar at the very end for maximum bite. Mine made this way was very spicey.
