I hadnt thought about it until now

However someone bought to my attention yesterday, that lemon, lime and bitters has alchohol in it, and that is the only soft drink I can keep down. So a guess a couple of rum balls wont hurt

BTW : I never add rum to rum balls or alchohol to trifle
Lemon lime and bitters is likely to be the same alcoholic ratio as rum balls - prob less. The bottle of bitters is approx 50% alcohol and there dislike a couple of drop s in the glass. It is safe to drink
