Now a matter of some seriousness, particularly at this time year. Sprouts. These seem to divide opinion as deeply as the notorious Marmite. Now I love sprouts. For me they are one of the great treats of winter - and not just for Christmas dinner. But I understand that some wimpish, finnicky eaters have a problem with them. Ridiculous.
[But don't open a jar of Marmite within my smelling range.]
