This is how to make the tastiest Licor 43 cocktail

I don't know if you have looked outside yet, but I hope you are jumping at the window as much as I am. The sun is shining and we are tapping 30 degrees today. Time to pull out that bikini and make your way to the nearest beach bed. Once you have plonked yourself there, there is really only one question left to ask: what are we drinking today? Very easy, because I only have one answer to that too. Something with Licor 43, grapefruit juice, lime and sparkling water....
