What is Spherification? How to Make Edible Pearls & Caviar at Home
Spherification is a simple kitchen technique that turns liquids into soft, jelly-like pearls with a liquid centre. It is often used to make edible pearls and caviar that add texture and interest to everyday desserts and drinks at home.
What Is Spherification?
Spherification is a kitchen technique that turns liquids into small, jelly-like pearls with a liquid centre. You often see spherification used to make fruit caviar, popping boba, or as a finishing touch on desserts and drinks. Home cooks like this method because it is easy to manage once you understand the steps and ingredients.
The spherification process works by forming a thin gel layer on the outside of a liquid while the inside stays fluid. This is what gives the pearl its soft burst when you bite into it.
At home, spherification typically involves blending sodium alginate into a flavoured liquid and placing it into a calcium bath. The outer layer sets almost straight away, forming edible pearls. It is similar to making jelly, but only the outside sets while the centre stays liquid.
How to Do Spherification at Home
If you are wondering what spherification is? It is a simple kitchen technique that turns liquids into soft, jelly-like pearls with a liquid centre. This method uses basic spherification, which is ideal for beginners and works well with juices, teas, and other flavoured liquids.
Ingredients (with Measurements)
For the flavoured liquid
-
500 ml fruit juice or flavoured liquid. Clear juices work best, such as apple, mango, or pomegranate
-
5 g sodium alginate
For the setting bath
-
500 ml water
-
15 g Calcium lactate or Calcium chloride
For rinsing
-
A bowl of clean water
Tools and Equipment Required
-
Digital kitchen scale
-
Blender or hand blender
-
Measuring jug
-
Mixing bowls
-
Dropper, syringe, or small spoon
-
Slotted spoon
-
Fine strainer (optional)
Spherification Step by Step
Step 1: Prepare the flavoured liquid
Pour the juice into a blender, add the sodium alginate, and blend until fully mixed. Let it rest for 15 to 30 minutes so air bubbles can settle.
Step 2: Prepare the calcium solution
In another bowl, dissolve the Calcium lactate or Calcium chloride in water. Stir until completely dissolved.
Step 3: Form the pearls
Use a dropper or spoon to gently drop the flavoured liquid into the calcium bath. Small drops create caviar-style pearls, while larger drops make bigger spheres.
Step 4: Allow the pearls to set
Let the pearls sit in the bath for roughly half a minute to one minute. A longer time will give a thicker outer skin.
Step 5: Rinse
Remove the pearls with a slotted spoon and rinse them in clean water to stop the setting process. Your edible pearls are now ready to use.
Spherification for Beginners: Common Mistakes to Avoid
Most early issues with spherification come from small, easy-to-miss details rather than the technique itself, especially when making edible caviar at home.
-
Using liquids high in calcium, such as dairy-based ingredients
-
Skipping the resting time after blending sodium alginate
-
Leaving the pearls in the calcium bath for too long
-
Choosing cloudy liquids when a clear finish is needed
Using the correct molecular gastronomy powders and paying close attention to timing helps prevent most of these problems and leads to consistent edible caviar with a clean look and texture.
Tips for Handling and Using Edible Pearls
If you are new to edible pearls, a few simple handling habits can help maintain their shape, texture, and finish. Paying attention to rinsing, storage, and timing makes a noticeable difference when using edible pearls at home.

-
Avoid storing pearls in plain water for long
Plain water slowly softens the outer layer, which can cause the pearls to lose their shape. -
Rinse after the calcium bath
A quick rinse removes any bitter taste from the setting solution and stops the pearls from setting further. -
Use pearls on the same day
Fresh pearls give the best balance between a soft outer skin and a liquid centre, creating the gentle pop that makes this technique enjoyable to eat.
Bringing Spherification Into Your Home Kitchen
Once you get comfortable with the basics of spherification, repeating the process with new flavours feels natural. Keep batches small, watch the timing, and make small adjustments as you go. With a little practice, edible pearls and caviar can become a simple and reliable technique in your home kitchen.
