A fave drink of mine a lot of years ago used to be a shot or two of tia Maria over the rocks topped up with pure fresh orange.
It’s taste just like Jaffa cakes & smarties so people call it either or. I call it a squaddies drink as the first time I was ever given the chance to try it, was at the squadron bar my brother managed in Germany. We were visiting both my brothers who based over there for a few years.
The drink tastes amazing!
please let me know if you give it a go!
