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.

Margaret, I haven't found the perfect time, the size of the leaves don't tell me anything. Last week I did use some, just scraping away surrounding soil and seeing the thickness of the root helped, the root was fairly thick, about the same as two fingers plus a little more. Getting it out is the hard part, the roots go down a long way so I cut the amount I needed and replaced the soil. Be careful if you do this because the root is very strong, a serrated knife worked o.k
