Cuba Libré With a Twist


This was so much fun to make and not hard at all, the longest part was waiting for the rum too cool to room temperature. These are also great to impress you guests. I will attach two links to websites that I use quite regularly one being The Red Spoon Company (This is a great site for the food additives, cooking equipment and ingredients). The other site is Molēcule-R (These guys do great little kits for people who want to have a go at molecular gastronomy).



– 300ml White Rum

– 300ml of Water

– 500ml of Distilled Water

– 400ml Of Your Favorite Cola

– 2Tbsp Caster sugar

– 1g Xanthan Gum

– 2.5g Calcium Chloride

– 2g Sodium Alginate

– 1 Pipette or Caviar Maker

– 1 Spherification or Slotted Spoon

– 1 Shot Glass (Preferably Clear)


You are going to need three bowls or containers to start. In the first bowl place the xanthan gum and the caster sugar and mix to combine. Next add the water and the rum. Blitz with a hand blender, cover and refrigerate for 60 minutes. In the second bowl pour the cola into another bowl and add the sodium alginate. Blitz with a hand blender and set aside for three minutes. In the last bowl you want to make a calcium chloride bath and to do this is quite simple, add the distilled water and calcium chloride and stir to combine.

Now comes the fun part, grab the two bowls with the cola in it and the calcium bath. Grab your pipette or caviar maker and extract the cola mixture. Next you want to drip the cola mixture into the calcium bath. Keep dripping the more you make the better your shot will look. Once you think you have enough, stir the pearls with a spoon to loosen them up.


Presentation. Get a big scoop of the pearls with your spherification spoon or slotted spoon and tip carefully into a shot glass. Take the Rum mixture out of the fridge and into a measuring jug (it just makes it easier to pour). Pour the mixture into the shot glass and boom! You have yourself a molecular Cuba Libré shot. Enjoy 🙂
