It’s so easy to to work with Agar Agar that I thought I’d get adventurous and mix two Molecular Mixology techniques and make a Piña Colada cocktail gel for this summer weather we’ve been having lately. This gel is a rum and coconut cream sphere encapsulated by a pineapple-berry gel. I envisioned the sphere made with the Reverse Spherification technique bursting in the mouth as you bite into the gel.
Reverse Spherification isn’t as complicated as I first thought. It’s a Molecular Mixology/Gastronomy technique that will make a tasty sphere of any liquid, preferably one with a high calcium content, that’ll burst in your mouth.
Most people experimenting with this technique will use a measuring spoon to form the spheres in the Sodium Alginate(Sa) solution. However, I never quite had the gesture down to do this so, I use a silicon mold to freeze the Calcium Lactate(Cl) solution first before I drop the would-be spheres into the Sa solution.
To make the coconut rum sphere:
- 1/4 tsp Calcium Lactate
- 100 ml Coconut Cream/Milk
- 100 ml White Rum (Malibu Coconut rum preferable)
- 1 Sachet (2g) Sodium Alginate
To make the Pineapple-Berry Gel:
To make the Rum-Coconut Sphere, combine coconut cream, rum and calcium lactate in a square based jar using a spoon or immersion blender. Once Cl is fully dissolved, pour into a silicon mold with a curved base and freeze for 12 to 24 hours. Alternatively, if you don’t have this mold you can use a measuring spoon.
If you use the silicon mold, un-mold the ice into a sodium alginate bath. Gently stir to avoid them sticking to each other. Leave them in the bath for at least 5 minutes to allow for the outer layer of gel to form. Please note that the longer you leave them in, the thicker the gel membrane will become. Once they’re ready rinse the spheres in some distilled water to stop the gelling process.
After this, you can place the spheres in the ice cube mold.
Add the mixture of Pineapple and Mixed Berry juice now. This mixture is made by boiling the two juices with a teaspoon of Agar Agar for 5 minutes. While still hot, fill the mold half way, wait a few minutes and then fill to the top. This will allow the sphere to sit in the middle of the gel as opposed to floating right to the top . The beauty of Agar is that it sets at room temperature. You can refrigerate this for a minimum of 1 hour to get the ideal result.
Cocktail gels are best served cold. I’m so happy with the result. It worked out exactly as i’d wanted. It’s the experience of a Pina Colada in one tasty bite!
Remember, drinking is always fun when it’s done responsibly!
