People are funny critters.
I was telling someone last night that I was going to sprinkle some brandy on my Xmas cake and they responded with "With my cake, two slices and you can't stand up".
Another friend swears that, after two of her sister's rum balls, you will not be able to drive.
Have they thought this through?
You need about 5 standard drinks to reach the legal limit to drive. I have done a few searches of rum ball recipes and the typical level of rum is about 5%. More or less.
Now a standard drink is 30ml for spirits, so to get five drinks worth of rum under your belt you need to eat 3kg (6.6lb) of rum balls in a hour.
And to loosen your belt.
I'm thinking not.
