2. What is the historical documentation?First documented by Unilever in the 1950s
3. How do chefs make those food bubbles?They mix a liquid with a special seaweed powder called sodium alginate, then drop it into a bath of calcium salt. The calcium makes a thin skin form around the liquid, creating a sphere.
4. Why did chefs start using spherification?Chefs like Ferran and Albert Adrià used it to separate flavors into little orbs, so people could taste a burst of flavor when the sphere pops, and to make dishes look amazing.
