How to make popping boba

This recipe explains how to make popping boba in flavors like watermelon, mango, and coffee using fruit juices or flavor extracts combined with sodium alginate. The flavored mixture is dropped into calcium lactate water creating gelled spheres that burst in the mouth. This method yields translucent spheres with liquid centers, commonly used as toppings for drinks and desserts.

Description

Making popping boba involves blending fruit juices or flavored liquids with sodium alginate powder to create a liquid mixture. This mixture is left to sit to remove froth, ensuring a smooth solution. Meanwhile, calcium lactate is dissolved in water to form a gelling bath.

The flavored sodium alginate liquid is then carefully dropped into the calcium bath with a dropper. Upon contact, a thin gel membrane forms around each drop, encapsulating the liquid inside and creating small spheres that resemble caviar. These spheres are removed after about one minute and rinsed in plain water to stop the gelling process.

Variations include using watermelon juice, mango with water, or coffee extracts to create different popping boba flavors. This technique uses simple ingredients and basic kitchen equipment to craft flavorful boba that add a distinctive texture and burst of flavor to beverages and desserts.

  4. In a separate bowl, whisk together the calcium lactate and cold water.
  5. Using a dropper, place drops of the watermelon/sodium solution into the calcium solution. You will see them instantly form into spheres. Using a strainer, remove the boba from the calcium solution and place them into a bowl of water after 1 minute.

Mango popping boba

  1. Place mango pieces, water, and sodium alginate in a blender and blend until smooth.
  2. Pour the mixture into a bowl and remove any bubbles from the surface with a spoon. Cover the bowl with plastic wrap and set it aside for at least for 4 hours or overnight.
  3. In a different bowl, use a whisk to combine cold water and calcium lactate until the water becomes transparent again.
  4. Use a dropper (either syringe or squeeze bottle) and place drops of the mango/sodium solution into the calcium water. They should instantly become spheres. One drop one time.
