.....Lofthouse's Fisherman's Friend!
It's no coincidence that the Dutch spend a lot of time outdoors (some of it cycling) and they have a serious appetite for liquorice (that's liquorice 'drop' not that squidgy crap).
Your morning commute will go alot easier with a Fisherman's Friend warming your noggin.
Maybe you tried these as a kid and thought they were vile, well our tastes mature over the years and I bet you'll like them now. Try you first one when your are stood outside in the cold.
