'spherification' on Serious Eats
Sweet dessert soups are common in East and South East Asia. I'm partial to those made with coconut milk, which make a silky base for inclusions of fruit, red bean, tapioca pearls, and jellies. Spherified fruit juices combine the best of these add-ins: intense fruit flavor with a dynamic, juicy texture. I used guava juice, but use whatever flavors (perhaps in combination) you like. You can even dilute flavored syrups (like ginger or cinnamon) in water for your fruit juice. Just stay away from acidic ones like lime juice, which in my experience do not set as well.
