How to Make Popping Boba Using Spherification
This popping boba recipe shows how to make juice-filled pearls at home using a simple spherification method that works well for beginners. The pearls gently burst when you bite into them, adding flavour and texture to bubble tea, mocktails, yoghurt bowls, and desserts.
Making popping boba at home lets you choose your own flavours, control the sweetness, and follow the process step by step, even if you have never tried this style of cooking before.
What Is Popping Boba?
Popping boba, also called edible pearls, is made by turning flavoured liquid into small, soft spheres with a thin outer layer and a liquid center. When you bite into these boba pearls, the shell gently breaks and releases the juice inside.
These pearls are made using specific spherification ingredients, which help the liquid keep its shape on the outside while staying soft and flowing on the inside.
How Spherification Works
When flavoured liquid mixed with Sodium alginate meets calcium, it forms a thin gel layer on the outside, while the inside stays juicy and runny. That’s how you get popping boba that actually pops instead of turning into jelly blobs.
Yes, it uses molecular gastronomy powders, but don’t panic. You’re not doing a science exam. If you can stir, wait, and drop liquid into a bowl, you’re good.
Ingredients List
Fruit Base
-
200 ml fruit juice or strained fruit purée
-
2 g sodium alginate
Calcium Bath
-
500 ml water
-
15g calcium lactate or calcium chloride
For Rinsing
-
Cold water
These ingredients are often included in a molecular gastronomy kit, though this method also works for anyone trying popping boba without kit if powders are sourced separately.
Tools and Equipment Required
-
Mixing bowl
-
Hand blender or whisk

Dropper, syringe, or squeeze bottle
-
Slotted spoon

Two medium bowls
Step-by-Step Popping Boba Method
This process is simpler than it looks. Once everything is prepped, making popping boba is all about gentle mixing and patience.
1. Prepare the Fruit Mixture
Add sodium alginate to the fruit juice or purée. Blend until fully combined.
Let it rest for 20–30 minutes so air bubbles settle.
2. Prepare the Calcium Bath
Dissolve the calcium powder in water and stir until completely mixed.
3. Form the Boba Pearls
Using a dropper or syringe, gently release drops of the fruit mixture into the calcium bath. The popping boba using spherification will form instantly.
4. Set the Texture
Leave the pearls in the bath for 30–60 seconds. Less time keeps the centre more liquid.
5. Rinse and Finish
Lift the pearls out using a slotted spoon and rinse them in clean water to stop them from setting further. Your homemade popping boba is ready.
Practical Tips to Avoid Common Mistakes
-
Always strain fruit juice to remove pulp
-
Very acidic juices may need adjustment
-
Keep drop sizes consistent for even boba pearls
-
Do not leave the pearls sitting in plain water for too long

Pomegranate Fruit Caviar

Fruit caviar uses agar agar powder from MeronKart to create firm, glossy pearls that hold their shape well. These pearls work nicely as a garnish for desserts, yoghurt bowls, and plated dishes. While the process may look dramatic, it is quite straightforward once the oil is properly chilled.
Ingredients
For the caviar
-
1 cup fresh pomegranate juice
-
1/2 tsp agar agar powder from MeronKart
-
2 tsp powdered sugar
For shaping
3/4 cup olive oil or sunflower oil, well chilled
Method
-
Chill the oil
Pour the oil into a tall glass or bowl and refrigerate it for 1 to 2 hours. The oil must be cold for the pearls to form cleanly. -
Prepare the pomegranate mixture
Add the pomegranate juice and sugar to a pan and stir gently. Sprinkle in the agar agar powder and bring the mixture to a boil, stirring until the agar dissolves fully. -
Transfer to a syringe
Once the mixture is smooth and hot, carefully transfer it into a syringe or dropper. -
Form the caviar
Slowly drop the mixture into the chilled oil. As the drops sink, they will set into small, round caviar pearls. -
Strain and rinse
Strain the pearls using a fine strainer and rinse them well under cold water to remove any oil residue. Set aside until ready to use.
The pomegranate fruit caviar recipe is a good option when you want neat, well-shaped pearls, but fruit caviar can be prepared using any fruit base depending on the flavour and colour you prefer. The method relies on setting agents rather than the fruit itself. Ingredients such as veg gelatin, vegetarian jelly powders, agar agar, or pure refined kappa carrageenan can be used to form caviar pearls.
