No, rarely. But as I hadn't signed in my response did not get captured. Here it is again, or something like it. As the thread had been take 'off course', it needed closing as my enquiries had received pertinent and helpful answers in regard to growing horsradish. I have decided to follow that advice. Have since bought ready made horsradish sauce from Mr. Waitrose - much safer. Don't need to discuss thongs per se, hardly enlightenng topic anyway.
