I love liquorice and my DH and DD hate it, it’s great if I get given some as I get to eat it all myself. In fact I’ve just treated myself to some and one of the types I’ve ordered are cola liquorice bottles (much to DD’s disgust as she loves cola bottles,) that sound delicious.
Peanut butter is another one I love and they hate.
DH and DD like black pudding but I can’t stand the stuff.
