I was never really fond of rum balls, probably because of the artifical rum flavouring used in the majority of the ones I tried. They tasted overly sweet and the chocolate was bland. Last year I got on with making rum balls and I haven't looked back since. They are now part of my regular Christmas baking. Running a close second to my shortbread.
The ones I made, pictured here, have a good quality chocolate and rum. The flavour is deep and rich and as for the rum... you can never have enough rum in them. These are great to give as a gift or a festive thank you treat when dashing off to one place or another over the holiday season. - JW
