These passion fruit spheres burst in your mouth releasing an intense hit of passion fruit puree. We've balanced the slight sourness of the passion fruit with a sweet chocolate soil and a sprinkling of chocolate popping candy.
We've opted to use reverse spherification to make these passion fruit spheres. Reverse spherification has come to be preferred over basic spherification because it is more versatile and the spheres are less fragile.

And as if spherification wasn't magical enough, we've also created chocolate soil from just 3 basic ingredients - chocolate, water and sugar. The chocolate crystallises as it comes into contact with the hot sugar syrup with spectacular results. To top it off, a sprinkling of chocolate popping candy ensures this dishes is a multi-sensory sensation!
For the passion fruit spheres Serves: 8
For the sodium alginate bath
- 500ml bottled low-calcium water
- 2.5g sodium alginate (0.5%)
For the chocolate soil
- 75ml water
- 200g caster sugar
- 80g dark chocolate couverture
- 200ml bottled low-calcium water (for washing the spheres)
- 40g chocolate popping candy (to serve)
- Black porcelain canape dishes (to serve)
- 10 small sprigs of mint (to serve)
- Spherification spoon
- Thermapen thermometer
- 1 tbsp measuring spoon
The passion fruit spheres
- Begin by making the sodium alginate bath. Mix the water and sodium alginate in a food processor on full speed for 1 minute, until evenly dispersed.
- Transfer to a bowl, ideally a bowl with a flat bottom and perpendicular sides. Cover with cling film and let it rest in the fridge overnight.
- For the passion fruit spheres, mix the passion fruit with the sugar and calcium lactate in a food processor on full speed for 1 minute.
- Add the xanthan gum and mix for a further minute on full speed.
- Refrigerate overnight to allow the air bubbles to disappear.
- When you are ready to spherify, prepare a bowl with 200ml water for washing the spheres.
- Fill the measuring spoon with the puree and pour it into the sodium alginate bath. Place the spoon close to the surface of the bath and flip the spoon to pour it in.
- Try one sphere at a time to begin with. Leave the sphere in the bath for about 2 minutes, gently moving it around and stirring with the spherification spoon.
- Use the spherification spoon to lift the sphere out of the bath and into the prepared bowl of water. Store them in this bowl and transfer to the plating dish once ready.
The chocolate soil
- Prepare a baking tray with greaseproof paper.
- Heat the water and sugar in a pan to 135°C. Use a thermapen thermometer to monitor the temperature.
- Remove from the heat and pour in the dark chocolate couverture chips. Stir with a whisk until the mixture crystallises.
- Tip onto the greaseproof paper and wait until cooled before using.
- Place a teaspoon of chocolate soil at the bottom of the canape dishes.
- Use the spherification spoon to delicately place the passion fruit sphere on top.
- Finish with a sprinkling of chocolate popping candy and a sprig of mint. Serve immediately.
