My wife and I enjoyed the painkillers so much, that we decided to make them at a family get together after we came back.
Getting the ingredients was a bit of a scavenger hunt though.
Had to go to a large super market to find the cream of coconut - which, oddly enough is very thick, and comes in a squeeze tube.
And none of the local liquor stores had Pussers Rum. They could special order it in, and told me it's pretty expensive.
So, I just used regular old (much cheaper) dark rum.
Still was quite yummy!
