Yes I remember liquorice roots ... brown sticks that tasted of ... liqourice - you had to chew them forever ... I preferred the black processed stuff we used to call Spanish in Yorkshire. For a couple of years in my school summer holidays I worked at Bassets Liquourice Allsorts factory in Owlerton, Sheffield - at the end of it I thought I would never touch another piece of liquorice or liquorice allsort. You wer allowed to eat as much as you liked whilst at work - as long as you did not put in in your pocket or try and steal it. Most people tired of eating it after a few days ....
You can still buy Liquorice root:
