Ingredients in Watermelon Popping Boba
Here’s what you’ll need to get these juicy spheres popping:
Watermelon Juice: The fresh, sweet star flavor.
Sodium Alginate: A natural gelling agent to form the boba spheres.
Calcium Lactate: Helps the juice gel and form the popping outer layer.
Sugar: To balance and enhance the sweetness (optional, depending on juice sweetness).
Water: Used in both juice preparation and calcium bath.
Instructions
Let’s dive into the steps to create this flavorful masterpiece:
Prepare Your Juices
Strain fresh watermelon juice to remove pulp. Sweeten lightly with sugar if desired, then mix in sodium alginate until fully dissolved.
Make Calcium Bath
Dissolve calcium lactate in cold water to create the setting bath.
